A MySpace for Gamers and Game Devs
Check out The Great Game Experiment, a community site especially for gamers and game developers. Members can introduce their favorite games, add new games, meet other gamers/developers etc. The site also focuses on Independent Game Developers, after all it was Jeff Tunnel of Garage Games who breathed life into it (The same Jeff Tunnel of Dynamix fame btw! Games like Project Firestart and Rise of the Dragon come to my mind).
Developers can introduce their creations and find other developers – both professional and hobbyist – to get working together on a project. Games made in Flash are welcome and there’s even a category for it.
