Part of the reason I posted something about Wikipedia, is that I'm probably going to be at Wikimania 2006. I'll also definitely be at the Chinese Finance Association meeting also in Boston in October, and I might stick around for the ISEAD quantitative finance conference right afterwards.
I've been noticably less shy and anonymous with my online personas since I got back from MIT a few weeks ago. I'm not sure exactly why. I suppose the fear that I had before was that I'd be publicly humilated at some point, and I think this is the fear that keeps a lot of people who have something useful to say from saying it.
