TEDx you mean. Which matters quite a bit, given that there are effectively no restrictions on who can give a TEDx talk :p
Which isn't to say that it's useless, just that the "TED" gatekeeping role isn't actually happening here, instead the gatekeeper is "people who have heard of TEDx", which is very different and imo quite a bit less useful.
