@David Bisset - Well, Chris came out and said that WordCamp LA 2013 was organized by first timers, which is why I added it to my post. At any rate, the buck stops at the WordCamp organizers and if a bad presenter gets on stage or the presentation has offensive slides, the onus is on the organizer, not really anyone else. For those reasons and more, WordCamp organizers are the first and best line of defense from speakers like the ones Chris describes from getting on stage.

@David Laietta - Orlando is on my possibility list. I just haven't nailed it down yet!
