Might be in sf this summer, I want as much experience as possible

Hey everyone,

I'm an international student, going to college at Georgia Tech. I've currently got an internship in NY for this summer, but due to the ridiculous bureaucracy of the US government, I may not be able to take it. If I can't, I'll probably be in San Francisco this summer, working on a startup with a friend. We also really want to go around and check out different startups in the area. Can anyone give me tips on finding cool startups to work for and hang out with?

Cheers!
