I think part of the reason for having ~50% of the speakers being "entertainment" is to give people at the event a break intellectually, and to get to socialize with other attendees. It doesn't produce great video for home viewers, though.
I think I might go to the BIL conference (free, and run in parallel) and shoot video/live stream it.
David Brooks, Jason Mraz, someone from Pepsi, puppeteers??? Mindblowing.
I actually listened to the Ford Motor dude's presentation and it was awful. It seems like TEDTalks now are just a way for business people to feel like they changing the world for the better (when in actuality they usually aren't). Instant gravitas.
