There were lots of people I saw at OSCON too briefly, or said hi to in the halls. Off the top of my head, this includes Andy Lester, Bill Odom, David Wheeler, Stas Bekam, Phillipe Chiasson, Jamie McCarthy and so many more. There's never enough time at these conferences. On the flip side, I actually met some new people and had a great time hanging out with them, including Martin Galese, Chris Dawson, Keith Lofstrom, Alex (last name I cannot remember), Schuyler Erle (who I missed last year), and others.
That means that next year there will be even more people I want to talk to and don't.
All in the all, the conference was really great on many levels. I think my talk went well, and I was happier with it than others I've done recently. I also attended some really interesting sessions and got turned onto the whole GIS thing by Schuyler, Jo, and Rich Gibson. This prompted me to go to the PostGIS session (great talk, BTW), and I'll be looking into the whole GIS thing quite a bit in the near future, I think.
Not enough Go, unfortunately, just one game with Autrijus. It's hard to identify other Go players without screaming out "anyone want to play Go" in the hallways or something like that.
