Google Buzz goes after Facebook, Twitter

Google plunged into the world of social networking on Tuesday, melding pieces of Facebook and Twitter into a new feature, Google Buzz.

Buzz, which will work through the popular Gmail service, will allow users to post status updates, photos and links to members of their network -- as well as pull in their activity on other sites like Twitter, Flickr and Picasa.

Google spokesman Bradley Horowitz said the service, which was rolling out to some Gmail users Tuesday afternoon and should be available to all in the next couple of days, aims to weed out what he called the clutter of other networking sites.
