Twitter for The Gamer, Raptr
So far we have Facebook, Myspace, and the list goes on and on, and now we have Raptr. The difference is that Raptr is meant specifically for the gamer in all of us. Much like Xbox Live, Raptr allows us to track our friends and what games they are playing.
The thing that sets Raptr apart is that it tracks your games on Windows, Mac, Xbox Live, Steam, World of Warcraft and shares it not only with the Raptr client, but with Facebook, twitter and Friendfeed.
