Xbox 360 and Community Server stuff
My buddy Dave has been building sites based on Community Server 2.0 like it was going out of style. He loves the power and flexibility. A couple of his sites are Xbox 360 Poker and 360 Deals. He's actually having a Gamer Score Whore contest over at 360 Deals for a free game (apparently that's a term from within Microsoft according to Major Nelson). If you are interested in seeing how your Gamer Score stacks up against everyone else, there is a cool site written in .NET that will tell you (they must pull in gamertag info from a web service?) called Top 360 Tag. Here is a link to my gamer tag stats.
