Yes, yes, yes. It has been a VERY long time since I posted.
One small project I've been playing with (to learn more about OAuth and facebook/twitter integration) is A good way to find other people who want to play desktop roleplaying games, card games, etc.
The premise is simple, and the site is VERY basic - it allows you to list your interests and to find people nearby who share those gaming interests. I plan to create a similar site for pickup sports ("tennis, anyone?")... but not until I have twitter firnally integrated.
