The Webware 100 winners

(Credit: CNET Networks)

We still might not exactly be able to define "Web 2.0," but we certainly know it when we see it. The CNET Download.com team has been gradually building a catalog of more than 2,300 editorially selected Web-based software products in categories such as Audio, Bookmarking, Security, and Social Networking.

Almost everyone uses a Web-based e-mail client like Yahoo Mail, Gmail, or Hotmail, and I know that many users are shifting from Microsoft Excel or OpenOffice.org Calc to Google Docs & Spreadsheets for their basic spreadsheet needs, or for sharing documents with friends, family, and colleagues. Web-based multiplatform chat client Meebo has the potential to become the Trillian of the new generation.

Fellow CNET partner Webware.com covers the ins and outs of the Web 2.0 sphere daily, and the site has just released the winners of its second Webware 100 competition. Site users picked the winners from thousands of submissions.

There are 10 champions in each in 10 categories. Some of the names--Flickr, Last.fm, Facebook--are obvious industry leaders, but you're much less likely to be familiar with others like DeviantArt, Stardoll, or VoiceThread. Regardless the level of your Web 2.0 savviness, the Webware 100 winners are likely to provide everyone with new sites to explore or cool products to keep an eye on.

Have you tried any Web-based analogues for your favorite Windows applications? If so, which are your favorites? Do you have privacy or security concerns about online software? Tell me about them in the comments.
