If you ever decide to put together a social network dedicated to games by gamers (or people who want to play them), please let me know. I have a half dozen half-developed HTML5 games because I can't figure out how I would make enough money to pay the hosting bills. Would love to team up with someone who can build a platform that I could put these on.
I could do these as Flash of course (did do so with one game a couple years ago), but I can't say I'm interested in putting in library after library of ads and optimizing Actionscript to support a shrinking audience.
Amusingly enough, while they do have a small list of HTML5 games, there is nothing in their documentation that talks about how to get one to them. The single reference is to using an iFrame to put their API onto your game that is hosted at another URL.
I am hopeful they, or Mochi, or someone like them will come along and provide a true HTML5 solution like the Flash folks already have. But I suspect we are getting rather off-topic here :-)
Maybe not exactly what you meant, but Raptr employs video game players (including a few pro/ex-pro players), and is a social network for video game players.
