And more to the point, what are they saying? There are some sites that can help you find out fairly easily. The newest, Confabb, lets anyone upload a meeting's particulars, and post a comment about the meeting. Another one is Eventful, which has similar features, as does Upcoming. I see that Expo! Expo! is featured on Confabb, but no one's said anything about it yet. I'm attending for the first time this year, so I'll keep an eye on this to see what, if anything, people have to say about it pre- or post-show.
