I really like that Openfeint Feature in games and there is still things missing in it like Add Buddy button when you go into another persons profile from the highscore list so you could add them. They should have a feature like games that have Co-op multiplayer [which is a nice way to play with a buddy] and then the feature should be like selecting someone from your buddies list that have the same game, you could send them a Game Invite from that Push notification Feature and they could join with you so the both of you could team up and beat levels together. And last feature they should have is a Online Now or Not Online feature so you could know who is online and who is not. But i dont know if they have that but if they do, then they should add the other two. PLUS.... a OpenFeint Username Search Feature to add someones OpenFeint Username without needing to go into that Twitter or Facebook stuff.
