I met my co-founder through an IRC chat room specialising on the topic. He was the only other one still there until 4am. After our initial meeting to check out his personality and make sure he wasn't a maniac, I had another meeting with him where I asked him a bunch of technical questions. I did the same thing with three or four other people, it was obvious by his reaction to my process we were going to get along well.
