Google Buzz

With Google Buzz you can automatically follow the people you email and chat with the most in Gmail. Publish your ideas to the world or just to your closest friends. Comments get sent right to your inbox so it's easy to keep the conversation going. See thumbnails with each post, and browse full-screen photos from popular sites. Import your stuff from Twitter, Picasa, Flickr, and Google Reader. New posts and comments pop in as they happen, no refresh required. Buzz recommends interesting posts and weeds out ones you're likely to skip.
