>The panels I did see, the moderator (William Osman) didn't do a very good job moving through questions, so very few people got to actually ask anything.

Panels are a pretty mixed bag at conferences in general. So many panelists are reiterating talking points, they're repetitious a lot of the time, they're too polite and in agreement, and audience questions are often in the vein of not so much a question but a comment. I have seen good panels but I often avoid them as a rule.
