I think the problem with this conference is a lack of hard chairing: too many speakers are getting away with dodging hard questions and pretty straight product plugs, and the restlessness in the audience is palpable. These are some good speakers: they need equally good moderation to get the best out of them.
Mind you, better air con in the hall would help, too…
Update: an example: "Where are your users coming from?" "Everywhere." And then he changes the subject. Aaargh.
