Not sure how I just now learned about Raptr but it's the greatest thing since sliced bread. Integrates your steam, xfire, xbl, psn, facebook, twitter, etc. accounts into one gaming messenger platform. It's like xfire but taken to the next level. You download the app just like xfire then integrate all of your other accounts. Plus you get a sweet profile page.
