Google Buzz developed by Google

Google Buzz is a social networking and messaging tool from Google, designed to integrate into the company's web-based email program, Gmail.[1][2] Users can share links, photos, videos, status messages and comments organized in "conversations" and visible in the user's inbox.[3] Buzz enables users to choose to share publicly with the world or privately to a group of friends each time they post.[4] Picasa, Flickr, Google Reader, YouTube, Blogger, FriendFeed, identi.ca and Twitter are currently integrated. The creation of Buzz was seen by industry analysts as an attempt by Google to compete with social networking websites like Facebook and microblogging services like Twitter.[1] Buzz also includes several interface and interaction elements from other Google products (e.g. Google Reader) such as the ability to "like" a post. Google executive Sergey Brin said that by offering social communications, Buzz would help bridge the gap between work and leisure,[5] but the service and its rollout have been strongly criticized for taking insufficient account of privacy concerns.[6]
