That's a very good question, Factotum. We've debated that internally quite a bit. Victoria has a vision for starting a panel with Q&A days before the panelists arrive so their audience can have time to consider & submit questions. That way, when the panelists arrive, they already have some good audience questions to consider.
I didn't do it that way with Tab's panel partly because with him on assignment I'm not sure we'll get a hard start date until right before he's ready.
In prep for his panel I watched Gorillas in the Mist last night. No wonder he and Anna Hamilton Phelan were nominated for an Academy Award. So powerful.
