Windows live Planet is a social network from Microsoft India to help you find people with similar interests as you. You can also “Populate Your Planet” as they call it by importing contacts from the social networks that are connected to Windows Live (Facebook, Myspace, LinkedIn, Hi5 and Tagged), just as you can on your Windows Live Profile. The site also makes use of the Messenger Web Bar, so you can chat to your windows Live contacts without leaving the site.
