Wow, thanks. I'm fairly new to the area, and my startup occupies the majority of my time, so I have met few other founders so far. I'll have to leave my cave from time to time to hit some of these.
Check out @startupgossip on Twitter. I'm trying to post most of the events there. I also post stuff on my blog at sanjayparekh.com (altho I've been slack lately) when it comes to events I'm running. Start coming to events and you'll meet a ton of us who are in and around Atlanta doing startups.
Hmm, spend most of your time in your cave. What Brian said is right. There are so many events that it's easy to get caught up in the scene and spend more time talking about startups than actually working on one.
