I attended a Mensa meeting. It seemed around the level of a small regional science-fiction convention. Not really enough for me to have conversations with people.
I went to Orbital 2008 in London largely in the hope of having such conversations, and despite IIRC 1500 attendees I found it a lot harder than I had hoped. I suspect that I could do better in future by making more advance effort to find the right people and bring them together; I’m inclined to try to do so for Orbital 2010.
