Word from the LA Times is that Google plans to phase out its Gears plug-in in favor of HTML5 when it comes to augmenting browser abilities. The precise details of its enthusiasm for the plug-in aren't clear yet, but the general trajectory is no surprise.
Google, along with Mozilla, Opera, Apple, and some other allies, has been agitating for features that can make browsers and the Web into a more powerful foundation for Web sites and Web applications. Gears was an early Google effort in this area.
But Gears emerged in 2007--back before Google released a browser of its own, before the World Wide Web Consortium had put its full weight behind HTML5, before HTML5 had gotten the traction it now enjoys as an official standard in the making, and before Microsoft took interest in contributing to that standard.
It's clear things are different now, and HTML5 is solving the same problems Gears set out to fix, and a healthy cooperation is under way for future Web standards work.
Perhaps most notably that included the ability to store data on a PC so a Web application could work even when disconnected from the network--Gmail and Google Docs being the biggest examples. But that's solved by the local database work in HTML5 that's now arriving in browsers. HTML5 also provides for interfaces with files for better uploading geolocation to let a Web site make use of a person's location.
Various HTML5 elements are just beginning to arrive in Web browsers, and widely used browsers such as Internet Explorer 6 don't have any support at all. But the difficulties of getting people to install Gears or other plug-ins means that built-in browser support probably will reach more people sooner than Gears.
Google has given plenty of signals it's happy to direct Gears energy into HTML5. It proudly demonstrated offline Gmail using HTML5 storage last May at its Google I/O conference, for example. And regarding its O3D and Native Client plug-ins, which accelerate 3D and regular computing processes in a browser, Google developers have argued such technology should be built into the browser, not handled as a separate plug-in.
Google's official position, quoted in the LA Times, is as follows: "We are excited that much of the technology in Gears, including offline support and geolocation APIs, are being incorporated into the HTML5 spec as an open standard supported across browsers, and see that as the logical next step for developers looking to include these features in their Web sites...We're continuing to support Gears so that nothing breaks for sites that use it. But we expect developers to use HTML5 for these features moving forward as it's a standards-based approach that will be available across all browsers."
It was clear from talks at Google I/O that Google sees as a proving ground to try to advance Web technologies and counts it as a victory when Gears technology arrives in HTML5. The only real question in my mind is whether Google will continue to use Gears to develop Web technology it hopes will later sift down into the standards world.
Microsoft has begun a campaign to actively urge users of its 8-year-old Internet Explorer 6 browser to upgrade.
After launching IE 8 in March, Micosoft has concurred with critics that IE 6 is outdated. Many people have dropped the older browser, but the remaining users are often the tough cases--those who don't have a choice because of corporate computing policy or who aren't tech-savvy enough to realize there's a reason to move on.
This eBay 'Web slice'--basically a live bookmark in Internet Explorer 8--is part of Microsoft's effort to get people to upgrade from IE 6.
(Credit: Screenshot by Stephen Shankland/CNET)It's this latter population Microsoft is targeting with a campaign that runs through June 2010 that touts its own IE 8 as a better alternative. The campaign's first visible elements are a video aimed at online holiday shoppers and a Web slice to promote daily deals at eBay. Web slices are basically live bookmarks that can show miniature Web pages in the browser.
"What we're doing with the outreach is help users understand how to protect themselves against social engineering threats that exist and to help people understand how Internet Explorer 8 puts people in control of their own privacy online," said Ryan Servatius, senior product manager for Internet Explorer. Security was one of the big problems with IE 6, and Microsoft now boasts that security features in IE 8 block 2 million malware sites a day.
According to Net Applications' statistics, Internet Explorer 6 is still the most widely used browser, with 23.3 percent share of usage in October, followed by IE 7 at 18.2 percent and IE 8 at 18.1 percent. The newer browsers are gaining on IE 6, but so are rivals including Mozilla's Firefox, Apple's Safari, and Google's Chrome.
Web developers often gripe about having to support IE 6, which doesn't support many modern features for more sophisticated Web sites and even applications. Microsoft acknowledges that it's holding back development of the Internet, too.
"The best thing a user can do to advance the Web is to help move people off IE 6," Servatius said.
Of course, many will upgrade to IE 8 by buying Windows 7. IE 6 was the browser that shipped with Windows XP, which remains entrenched, but there are signs Windows 7 is a more compelling successor than Windows Vista. That could help the corporate customers move away from IE 6, Servatius said.
"As enterprises migrate from whatever operating system they're using today to Windows 7, that's going to help deprecate IE 6," he said. "What we're doing is working both with consumers worldwide and IT professionals to help them understand what the benefits of a modern browser are."
TweetDeck now doubles up profile pics on retweets to give original poster's credit.
(Credit: Screenshot by Jessica Dolcourt/CNET)Seesmic's Twitter reader app for Mac and Windows is looking at some serious renewed competition from TweetDeck.
The newly updated TweetDeck 0.32 (and AIR app for Windows and Mac,) packs in a host of changes that should make the desktop app more attractive to power tweeters. Chief among these is new behavior for retweeting, when users share a contact's tweet with their own list of followers in just a click. TweetDeck supports two formats, the "new style" that spits out an identical post and displays both your photo and that of the original tweeter, and the "original" style that lets you edit before you post the duplicated message. We like that TweetDeck can remember your preference, or that you can do nothing and choose fresh each time.

The new TweetDeck also incorporates Twitter Lists for the first time, a grouping feature that Twitter launched about a month ago. Just as you can manage individuals on TweetDeck, you can also manage lists and omit people on them that you don't directly follow. You're able to create new lists from scratch or from a list you already have.
In addition, tweets that include geolocation information now pop up with a yellow pin at the bottom of the message. You can click the pin to expand an embedded map. We haven't seen any of these show up in our lists yet, but the concept of convenience is similar to what Yahoo Messenger already does when it embeds photos and videos into chat windows. We hope that's next here, too.
Adding and expanding on Twitter features isn't TweetDeck's only move. The update also pulls the LinkedIn social network onboard, which means you can now read status streams from LinkedIn, Facebook, and MySpace in TweetDeck's column view, in addition to tracking streams from various Twitter accounts.
The version 0.32 update also makes its mark with a reorganized Add Column screen that replaces previous menu items with redesigned navigation for maintaining your Tweeting dashboard. The new TweetDeck includes numerous bug fixes as well; here's the changelog for more details.
Mozilla, determined to release Firefox 3.6 before year's end, is also determined to squeeze as many features as possible into the new browser.
The latest example: support for the File interface that adds more sophistication to uploading and some other chores.
Support for the feature is one of the 133 changes that arrived in Firefox 3.6 beta 4, which the Mozilla project released Thursday for Windows, Mac, and Linux.
The File API (application programming interface), a draft standard at the World Wide Web consortium, lets browsers handle files better. Among its abilities are uploading multiple files at once, showing thumbnail previews of images that have been selected for upload, breaking a long video upload up into chunks to protect against network interruption problems, and integrating with drag-and-drop Web applications.
While many software projects use beta testing periods to shake down their code, Mozilla isn't afraid to add new features as it goes. That can mean new ideas arrive sooner, of course, but it also can delay the completion date of the new version. What was to have been a quick Firefox 3.1 release was pushed back months as new features were added and the version ultimately was renamed Firefox 3.5.
For those who want to dig into the File interface, Mozilla offers a Web developer guide to using it.
The beta-testing periods aren't just important for debugging Firefox itself. New versions often don't work with older add-ons that people install to customize the browser, so beta testing gives some time for programmers to update those add-ons. Mike Belzner, Mozilla's director of Firefox, said 70 percent of add-ons are now compatible with Firefox 3.6.
There are a few sales over the Thanksgiving long weekend here in the U.S. with some developers slashing prices on many popular iPhone games. Huge iPhone game developer, Gameloft, is having a 99-cent sale on many of their popular game titles throughout the weekend. EA Games is also in on the action, offering price cuts to several of their big titles. Some games I've talked about here like Madden NFL 10, FIFA 10, and NBA Live are $6.99 for a limited time (usually $9.99) and there are a lot of other great deals. If you've been waiting for the prices to drop on some of the bigger games, now is the time to check out the iTunes App Store--you just might be pleasantly surprised.
This week's apps include a stylish clock app and a new Star Wars game that lets you relive some of the great moments of the original movie.
Choose from many different clock skins
(Credit: Screenshot by Jason Parker/CNET)PerfectClock (Free for a limited time) lets you display stylish-looking clocks on your iPhone screen that are perfect for when your phone is sitting in an iPhone Docking Station. The app comes with a handful of clocks you can choose from, or you can easily download free clock skins from within the app. Along with the beautiful designs, PerfectClock lets you set alarms, offers a number of different ways to display information on screen (date, month, day of week) and you can disable the autolock so the clock stays visible while you're charging it.
PerfectClock also comes with a number of ambient sound loops like rainforest sounds, ocean waves, and more. That way if your iPhone charges on your bedside table, you can set PerfectClock to play sounds of nature for a set amount of time (and even fade out) while you doze off. Overall, if you would like to use your iPhone as your main alarm clock and want a few more options, or would just like to check out some of the imaginative clock designs, you should download this app.
Try to avoid Darth Vader's crosshairs as you fly down the trench
(Credit: Screenshot by Jason Parker/CNET)Star Wars: Trench Run ($4.99) lets you relive the moments leading up to the destruction of the Death Star from Star Wars IV: A New Hope. You can play arcade mode and choose between a dogfight with Tie Fighters on the surface of the Death Star, or Trench Run, where you fly your X-Wing fighter down the trench evading Darth Vader and blowing away gun towers. The mission mode lets you fight your way through the ending moments in sequence up to firing your rockets in to the exhaust port and blowing up the Death Star. The controls are fairly simple: tilt your iPhone to steer your X-Wing and touch the right side of your screen to fire your weapons. You also can use a Force slow-down skill by touching the left side of the screen--a great option when the action gets particularly intense.
Though Star Wars: Trench Run is a fun diversion for a little while, the game doesn't offer much in the way of long-term replay value. Once you've done each of the missions and played the different types of game modes a few times, the action gets kind of repetitive. Still, with original sound effects and music by John Williams paired with smooth 3D graphics, this game will appeal to Star Wars fans who dreamed of doing the trench run so long ago (myself included). For more on Star Wars: Trench Run, check out Rick Broida's column here.

Whether you're doing a clean install of Windows 7, getting a new computer from a deep discount on Black Friday, or getting a full-priced present, you owe it to yourself to check out this revamped collection of the most essential freeware tools for Windows. The programs in the Windows Starter Kit 2010 will work on Windows XP, Vista, or Windows 7. These basics will get you up and running without even glancing askance at your wallet. If you're specifically looking for security tools, we've rounded up the best freeware security options in the Security Starter Kit.
There was much less movement in the Windows Starter Kit this year than in the Security Starter Kit, but there were still some changes that are worth calling out. Among the three recommended browsers, we moved Chrome ahead of Opera, although Firefox still retains top-dog status. Likewise, Mozilla's Thunderbird remains the best free desktop e-mail client. Had the Thunderbird-based Postbox remained free as it was in beta, we would've added it to the list.
In productivity apps, image editors, music jukeboxes, and video jukeboxes there was no movement at all. The GIMP is still the best Photoshop alternative that doesn't skimp on features, while Paint.NET is excellent for quick-and-dirty edits. We still recommend MediaMonkey as the best non-iTunes alternative, and we still recommend iTunes--despite its bloat--because it's still the industry standard. We expect these categories to be contentious because there are so many options available, so please let us know in the comments if you disagree with our choices.
TweetDeck and Seesmic Desktop (not pictured) debuted in the new Social Networking category this year.
(Credit: Screenshot by Rafe Needleman/CNET)File compression and torrent management didn't change either, although we added the impressive Trillian redo and Skype to the chat category. Social networking debuted as a new category, with two options: Seesmic and TweetDeck. In Utilities, we added Revo Uninstaller, threw in a second Notepad replacement, and replaced Launchy with Find and Run Robot.
The hard part of coming up with a collection like this is keeping it concise, especially when it comes to Windows utilities. The fun part, though, is hearing your thoughts. So check out the kit, and let us know what you think in the comments below.
Black Friday is almost upon us, and the steep hardware discounts mean new computers for many. To help you during these tough economic times, we've refreshed the Download.com Security Starter Kit for 2010. Although nothing can replace common-sense browsing, this collection of freeware security tools will help you protect new machines and old from pernicious threats, large and small. Longtime readers will notice that in addition to changing up our recommended antivirus program, we've fleshed out the Web browsing safety category, and made other changes as well. If you're looking for more than freeware security programs, check out the CNET Download.com Windows Starter Kit for 2010.
In this year's version, you can expect to see Avast chosen ahead of AntiVir as our most favored antivirus app. Despite its odd interface, Avast scored higher than any other freeware antivirus in a third-party test, and it doesn't skimp on protection, either, with e-mail, network, rootkit, and behavioral guards along with its top-rated virus protections.
We're still recommending Malwarebytes Anti-Malware for spyware removal, but we've also added PC Tools' standalone ThreatFire as an excellent way to strengthen behavioral detections and prevent spyware from infecting you in the first place. Recent improvements to the program have made it incredibly light on resources, and in our days of empirical testing we didn't notice it slowing down our computers at all.
New this year is the expanded in-browser security category. We've recommended five browsing tools that are available as add-ons, and we took care to make sure that they applied to as many of the major browsers as possible. However, Firefox's deep add-on toolbox makes it naturally the browser with the most diverse collection of security tools, so expect to see it heavily, although not exclusively, represented.
PC Tools' ThreatFire.
(Credit: Screenshot by Seth Rosenblatt/CNET)Firewalls used to be the forefront of security, but now they're just another tool you should have. Microsoft has made the native Windows 7 firewall impressively useful, but we realize that not everybody has Windows 7, and even those who do might want an alternative. This year, Online Armor joins Comodo on the list.
In Encryption, TrueCrypt remains the gold standard. The Thunderbird extension Enigmail joins it as a must-have tool for keeping your private e-mails as you intended them--away from prying eyes. In Parental Control, we've added OnlineFamily.Norton. It's not strictly desktop based, although to use it you must use its desktop hook, called Norton Safety Minder. Symantec has created what looks to be a unique and free approach that includes an emphasis on parental education and attempts to foster parent-child communication about how to use the Internet safely. We're of the opinion that anything that helps parents realize that browsing the Internet is far more than a TV with options is a good thing.
If you disagree with our security and safety choices for the Security Starter Kit, please let us know in the comments below.
Sometimes it's the little things that count.
The most prominent feature of Firefox 3.6 is Personas, which let you reskin the browser with thousands of different looks. But my single favorite change is a subtler change to the open-source browser's user interface.
CNET News Poll
Specifically, when you open a link in a new tab, it appears immediately to the right of the active tab. Before, the new tabs would appear to the far right of the strip of tabs.
Yup, that's it. For those of us who spend hours a day in a browser, though, the new tab behavior helps group related tasks together. I constantly shuffle among dozens of tabs, and the new approach automatically brings some organization to my cluttered life.
However, I know it's not everybody's favorite browser behavior. So along with explaining why I like it, I'll also take some potshots and share instructions on how to get the old way back.
Why it's better
The more things I do with a browser--and the number has increased steadily for years now--the more important it becomes to be able to find different tasks amid the chaos. Microsoft and Apple understand this, as evidenced by the new taskbar features in Windows 7 and dock expose in Mac OS X 10.6, aka Snow Leopard. Those features make it easier to pluck out the one window you need from among the many you may have open.
There's a pattern to how I spawn the dozens of tabs I use as a day progresses. On a variety of pages--Gmail, Google Reader, Yahoo Finance, somebody's blog post--I'll encounter a host of links to other pages. I'll middle-click my mouse button to open interesting pages as background tabs, then use Ctrl-Tab to switch to the new pages when I'm ready. I repeat this pattern many times a day.
With the old behavior, each tab appeared to the far right of the tab strip. That's fine when getting started, but when I've moved halfway across the list and want to open another batch, I want the new ones--call them children--to open next to their parent tab. When I go away and come back, or when I lose place juggling tasks, it's easier to find my bearings again.
It's like being in a library. When you're in the European history section, you don't want to find books on rewiring your house and on vegetarian cooking.
As a longtime Firefox user, I didn't realize tab positioning could be better. When I started using Google's Chrome, which introduced the new tab behavior to me, the scales were lifted from my eyes. I immediately could get to the next tab with a quick press of Ctrl-Tab on the keyboard rather than have to use the mouse to click over to the far end of the list. I use both browsers daily, but until the Firefox 3.6 beta arrived, the new-tab position had become a sore point for me when in Firefox.
The change is actually a big deal in a couple ways. First, even seemingly minor changes in software can be disruptive. Old habits die hard, and computer users wrestling with constant change can get angry when more is foisted upon them.
Second, though, browsers are assuming an ever greater role in what people do in their personal and professional lives, and keeping one's bearings is commensurately important. That's especially true for those people for whom a gaggle of browser tabs represents a collection of chores going on in parallel.
Internet Explorer 8 categorizes related tabs by color.
(Credit: Screenshot by Stephen Shankland/CNET) How the competition handles it
Tabs are now universal among browsers, but new-tab behavior isn't. Firefox and Chrome handle it the way I like best, but how do others tackle the issue?
First, let's look at Internet Explorer 8. Microsoft showed it understands some of the challenges of tab management in its latest version of its browser by coloring child tabs the same hue as their parents, but I have a gripe with how it works. Specifically, although child tabs get the same color as their parents for easy grouping and arrive to the right, grandchild tabs are the same color as child tabs. Similarly, grandchild tabs appear to the far right of the whole group of child tabs.
In my mind, I consider grandchild tabs a separate group from the child tabs. But with IE, grandchildren get the same color and position treatment as children. The only way to get a new color is to start a fresh empty tab There's no easy way to give grandchildren a new color without causing some confusion, though--should the child be the same color as the original parent or change color to be grouped with the grandchildren?
Next is Opera, which gives users a choice. By default, it opens new tabs to the far right, which I don't like, but in the Advanced|Tabs section of the preferences dialog box, you can check "Open new tab next to active." Huzzah!
There's a subtle change here I don't care for, though. Tabs always appear immediately to the right of the active tab. I'd rather have all one tab's children appear in sequence to the right. For example, if a parent tab is in position 1, then the first child would be in position 2, the second in position 3, and the third in position 4. Opening three child tabs in Opera leaves the parent in position 1, the third child in position 2, the second child in position 3, and the first child in position 4.
Last, there's Safari. It does it the old way I loathe with no option to change. Too bad.
Firefox can show thumbnail previews of new tabs, but I find them hard to recognize in front of busy Web pages.
(Credit: Screenshot by Stephen Shankland/CNET) Why it's not enough
Most browser makers are excited about the fact that their software is subsuming more and more computing tasks that previously ran on computer operating systems. But as browsers inherit this central importance, they also inherit some of the hassles.
The new tab positioning behavior in Firefox is a step in the right direction, but there's more that needs to be done. Moving from one tab to a related adjacent one, whether through a keyboard command or mouse clicking, is a minor change. But things get harder when you need to switch from one group of tabs to the next.
There's work under way here. Opera is perhaps the leader with the ability to show thumbnails as you use Ctrl-Tab to cycle your list of open tabs.
Firefox has been noodling with the approach too. It tried then dropped tab thumbnail previews earlier, but the technology is still present. Using the about:config system for tweaking the browser (more on this later), you can change the "browser.ctrlTab.previews" setting to "true."
But for reasons that aren't clear to me, I don't find this effective either in Firefox or Opera. Perhaps I haven't used it enough, or the thumbnails are too small to be immediately recognizable, or they're just hard to see against the noisy background. There's a good reason that Apple dims the background most of the way to black when using Expose.
Aero Peek in Windows 7 lets the task bar show a glimpse of Firefox and IE tabs.
(Credit: Screenshot by Seth Rosenblatt/CNET)Windows itself is helping, too. The new taskbar in Windows 7 can show individual tabs, once browsers support the feature. It's in Internet Explorer 8, and it's in the new Firefox 3.6 beta.
Add-ons such as Firefox Showcase can further tweak Firefox. (Indeed, for a wealth of options, check Mashable's handy Firefox tab management guide.)
More interesting to me, though, is work under way to expand Firefox's "awesome bar" abilities. Today, typing in it opens Web pages and retrieves ones you've already visited or bookmarked. In the future, it could be able to move you to another open tab, too. I'm a keyboard guy, so particularly appreciate this idea.
You can get a taste of the idea now. If you've enabled the "browser.ctrlTab.previews" option, hitting Ctrl-Shift-Tab will not only show you thumbnail previews, but will put a cursor in a search box.
Typing the letters of the Web page name will winnow down the thumbnails. For example, typing "netap" will cull my open tabs so only Net Applications and NetApp show. If you have a bunch of similar tabs all open, this might not help much, of course.
However, the feature only works with the tabs of one browser window, so if you can't use it to search among other browser instances.
How to get the old way back
Perhaps I've convinced you that the new approach is better. But perhaps not--in which case I encourage you to share your thoughts in the comments so people will hear more than my opinion.
For those who don't like the new tab positions, you can revert to the old method.
To get the old style back for new tab position, use Firefox's about:config system.
(Credit: Screenshot by Stephen Shankland/CNET)First type "about:config" in the Firefox address bar. You'll get a warning that you're tinkering with Firefox's innards and you should be careful, but this isn't brain surgery, so don't be frightened. Click the "I'll be careful, I promise" button, and you'll see a big list of all the browser settings that can be tweaked.
Next, in the text box labeled "Filter:", type "tabs.insertRelatedAfterCurrent"; you should see just one entry below. In the column marked "Value," double-click on the word "true" to change it to "false." You're done.
But I'd encourage you to at least give the new way a try. If you don't like it, you can always change back.
Mozilla Messaging has released the first release candidate of a Thunderbird 3, software it hopes will significantly improve how people read, write, catalog, and search their e-mail.
Mozilla released the software Tuesday for Windows, Mac, and Linux, several days later than predicted earlier this month but close to a year later than Mozilla planned in 2008. A final version of Thunderbird 3 is expected not long after the release candidate.
Thunderbird 3 has been years time in the making. For its next versions, the Mozilla Messaging group hopes to release new versions more frequently, said Mozilla Messaging programmer Dan Mosedale.
"Part of the plan for Thunderbird is to move our development process in a more agile direction...Rather than having super long releases, we'd like to release significantly more frequently than we have historically done," said a draft Mozilla proposal for what to do in the post-Thunderbird 3 era Mosedale posted. He proposed major Thunderbird releases every four to six months, starting with version 3.1, and also laid out some ideas for Thunderbird after version 3.1.
Thunderbird 3.0 adds a variety of features, according to Mozilla and the Thunderbird 3 RC1 release notes:
A more elaborate search option to locate specific messages. People can employ a variety of methods to sift the wheat from the chaff.
An e-mail archive a la Google's Gmail. Rather than filing every message in a folder, an organizational technique that can be hard to maintain with high volumes of messages, people can move them out of the inbox into the archive where search can find them later.
A streamlined interface that cleans up the toolbar and moves some of its functions to the frame around e-mail messages.
A new plug-in system designed to be easier to use to replicate some of the success of the Firefox browser. The browser, by the way, is built in so plug-ins can use it.
A tabbed interface that can reduce clutter of e-mails, e-mail folders, and other tasks. A tab can, for example, house a version of Yahoo's online calendar.
An easier process to set up new e-mail accounts. The software has preset settings for several e-mail services.
"Smart folders" that can be customized in a variety of ways. For example, users with multiple e-mail accounts can create a smart folder that provides a unified inbox for all the accounts.
An easier way to add people to the address book by clicking a star icon next to the sender's name.
Be sure to check the list of Thunderbird 3 RC1 issues if you're the cautious type.
The present interface for developers to upload their Chrome extensions.
(Credit: Screenshot by Stephen Shankland/CNET)
Google has opened up its gallery for developers to share Chrome extensions, a step that soon should make it easier for people to customize the open-source browser.
Aaron Boodman, a leader of the Chrome extensions effort, announced the move on a mailing list posting Monday, and programmer and "gallery master" Lei Zheng shared details in a blog post.
So far, only uploads are permitted. Google plans to let some testers use the gallery to download extensions, too "in the next few days," Zheng said. "We are making the upload flow available early to make sure that developers have the time to publish their extensions ahead of our full launch."
Extensions, a major asset of the Firefox browser and the headline feature of the upcoming Chrome 4 beta, let people modify the browser more to their liking. With them, the browser itself doesn't have to be bogged down with numerous features and configuration options that most people don't want.
One feature of Google's system is that add-ons are automatically updated on Chrome users' computers once the developer uploads a new version.
For developers, the extensions gallery comes with a set of terms and conditions.
One nugget in the legalese: expect Google to use a rating system, as it does for other sites including Android applications and YouTube videos. It's all part of Google's philosophy of using user data to help automatically manage its Web properties in a way that, the company hopes, will be helpful to those who use its sites.
According to the terms and conditions: "The gallery will allow users to rate products. Along with other factors, product ratings may be used to determine the placement of products on the gallery with higher rated products generally given better placement, subject to Google's right to change placement at Google's sole discretion. For new developers without product history, Google may use or publish performance measurements such as uninstall rates to identify or remove products that are not meeting acceptable standards, as determined by Google."
