I discovered today on my 360 that I can finally have last.fm (best thing ever trust me im still blasting it through my astros as I type this) facebook and twitter. It makes me happy that Microsoft realized that they weren't reaching the right market and it was stupid to exclude most of the teen market based on the fact that they had "child" accounts. It was simple just "parental" ( i don't think my parents even know the password) authorization and then I was in. Pretty Rad. 
 
Oh by the way if you read this in the forums this is a heads up to everyone who hasn't at least checked this stuff out yet I suggest you do last.fm is pretty rad and if you're into facebook and twitter hardcore and don't mind flaunting your blantant geek then you can have fun with those i guess. 
 
Also I want a Giant Bomb app for my dashboard
