Last year at DragonCon I was on a typical panel (I've done variations on this one at too many conventions, imho). The moderator was an old friend of mine, Keith, and he recorded the panel. He was not quite as skilled/experienced as some moderators I've seen, but all in all, he did pretty well. You may find the tape of the panel here:

In the still shot, I am the chick on the left. In the tape, my voice is the one that starts talking about paramilitary groups and then later about firefighting. (So you can figure out which one is me.)
Anyway. So this is the type of thing I do when I go to conventions.
P.S. This thing is about an hour long! (You've been warned. You can always abandon it mid-panel.)
