I came across this community site: 360voice. They offer something really cool to hardcore Xbox360 gamers:
360voice is a leading online community for the Xbox 360 with a twist. Using unique technology, the data from your Xbox Live gamercard is transformed from a snapshot into a rich history of your gaming, told in blog format from the perspective of your Xbox. This allows for conversations around specific daily achievements and events like gamer score increases and your most played games. In addition to the blog content, users can interact by leaving comments, compete in gamer score challenges, and gather badges for various site and cross-game accomplishments.
They boost about 145k member keys, totalying 1,780,398,839 gamescore (many pro-gamers)
I love this concept: Your game playing turns into a automated blog post that your community of players can read, and keep up to date with your gaming interests; how you did; what you're into that day. You can connect with other community members with similar gaming interests and challenge each other.
The site is run by Trapper Markelz (ChangeAgent), Stephen Sopp (Fatty Chubs) and David Larrabee (Squidpunch). For fun, listen to their latest podcast...these guys know their stuff.
