The top10 Innovative Companies in Web 2.0

There is a post in fastcompany.com this month, ranking top 10 web2.0 companies.
Although some of them may not be players in Web 2.0(it depends on the defenition of "web2.0")and criteria is not clear, all of these companies have outstanding concepts. All of these are very famous but if there is a company you don't know, it's worth checking it.

1. 1.Google: With Google Docs and the new Chrome browser, the search titan continues to take aim at Microsoft.


2. 2.Facebook: The social network that everyone loves to hate (but secretly loves anyway) overtook MySpace with 150 million active users.


3. 3.Digg: More than 35 million visitors per month submit 20,000 stories a day to the site. A recent $29 million financing round will keep the crowd thumbing through the downturn.


4. 4.Twitter: The microblogging phenom is adding up to 10,000 users a day, with the likes of The New York Times, JetBlue, and Lance Armstrong Tweeting.


5. 5.Meebo: More than 40 million users instant-message and chat across the Web through any format including the iPhone. A new partnership with Universal Music will connect chatters with artists, while a $25 million financing round in 2008 will fuel '09 expansion in Asia.


6. 6.FriendFeed: Relatively new to the life-streaming melee, FriendFeed aggregates every comment, posted picture, and status update from 59 Web services.

9. 9.Yelp: With 4 million user-submitted reviews of everything from corner cafés to dog groomers, Yelp can make or break local businesses nationwide.
