Panels at Otakon are what you make them, but it's generally a bunch of people sitting at a table in front of the room with a huge screen behind them. You're basically giving a presentation. People normally use powerpoints or show videos or do both. Most panelists seem to like doing a Q&A at the end, but I get the feeling it's because they've just run out of shit to talk about to eat up their whole hour.

The best panels I've been to are the ones who are run by people who are good at improv and just throw jokes into their presentations and make fun of each other and the crowd for a good portion of their time. When a panelist just sits around and talks in front of a powerpoint for an hour, it almost feels like being in a classroom and gets pretty boring. The Silent Hill panel in 08 was like that, and a lot of people walked out. Have fun with it as much as you possibly can.
