The talk went well, although there wasn't a huge audience. Of course I think that 15-odd different tracks is a little over the top for a conference.
Anyway, job done -- now I can enjoy myself.
There is some interesting lisp-y stuff this afternoon that I might attend, but at the same time is the mozilla talks, which I'm also interested in. Decisions, decisions...
