You could say I'm being picky here, but why not use the power of the Web which is a known solution for such situations? And btw real-world meetups often happen after online ones.
I don't have anything against real-world meetups, but I just came back from one, and there were presentations, but only a single project and you worked with people you already knew, mostly. So I didn't end up meeting much people, as chatting without a goal in mind isn't, err, my greatest strength. I'd really like something much more goal-oriented. The Six hour startup formula is really good, in that sense.
Thanks for the suggestions, though. I have heard of Free Hacker meetups in my area, for example, and I really should try showing up at one. Yet I think the goal is a bit different.
