Yahoo!'s new Web 2.0 Tool
If you're looking for a Web 2.0 tools that can help give your product, service, company, blog or whatever some extra legs, you may want to take a look at Yahoo! Buzz. Following in the same vain as Digg it allows individuals to become editors and select the articles that they would like to appear on the Yahoo! home page. According to Yahoo! this is the way the system works:
The buzz can be about anything - a great story on a major news site, an extraordinary bit from an obscure site, an intriguing video, or a fantastic blog that shouldn't be missed.
Instead of editors, people like you determine the top-rated stories.How does Buzz work?
A story is ranked based on its Buzz Score. The score is derived from search term popularity, the number of times a story is emailed from Buzz, and the number of votes a story receives.
Stories with the highest Buzz Scores may be published on the Yahoo! home page - you can impact what millions will see on Yahoo!
It's too early to say how this will develop but Yahoo! does tend to buy/develop some good Web 2.0 companies: Yahoo! Answers, Del.icio.us, Flickr, Upcoming. I have started to see some Yahoo! "Buzz Up" buttons on blogs I read - Guy Kawasaki is a case in point.
