At the pub afterwards, about every other person I met was working at a startup - especially later on when it wasn't so packed. The pile of business cards I'm going through now reflects this. Perhaps there was some self-selection amongst the people who stayed on at the pub for a while? (I regret that I missed the talks - unfortunately I was held up by a meeting that ran late).
