Featured Freeware: Twhirl
Built on Adobe AIR, Twhirl is a stand-out Twitter service that rolls the functionality of many ancillary services into one. For example, Twhirl automatically posts TinyURLs in place of long URLs, sends photos to TwitPic, and searches for Twitter topics using a built-in TweetScan engine. In the settings, you can configure Twhirl to cross-post updates to Jaiku and Pownce, much like the service Ping.fm.
Though cheery, the interface is also economical, providing extensive options for viewing and updating statuses and messages for all your Twitter and Friendfeed accounts without overcrowding the small screen. The preferences let you customize your receipt of tweet alerts, the program font, and network pings, but not the app's skin. Twhirl lacks options for dark, sleek, and multicolored looks. Though there are quick icons for sending messages and unfollowing a user that appear when hovering over a buddy icon, there's definitely room for improvement.

This is a direct quote from the article which explains what Twhirl does. You just need to read between the lines to understand the technical jargon beneath it. For example, the article explains that Twhirl 'is a stand-out Twitter service that rolls the functionality of many ancillary services into one'. Those ancillary services are then explained in the quote above, before going on to describe some of the more 'visual' details such as the interface.
