Excellent work. I've seen a lot of event sites and this one is the most concise and efficient. Seems to pull a lot of events! Would be nice if you could facebook integrate your friends events too.

I think you're getting the HN hug right now. Submitted a registration form never got the e-mail. I can't click any of the categories (like business for example). Changing the radius would be nice. Metric vs imperial for the 'muricans.
