I don't think we need another vehicle for the "spread of ideas". We have the internet for that. Everyone and their dogs have a blog on which they can detail the minutiae of their crackpottery. The reason I used to like TED is that they curated new and solid ideas that may have buried in the internet noise. In other words, they filtered out the noise and gave me the signal.

What now? Well, browsing a random TEDx video is about as informative as watching a random youtube video. Except that you can't listen to Pink Floyd on TEDx, too bad.

Sorry if the tone is a little annoyed, no harm intended..
