I've lost count of how many times someone has complained about an overly political, low quality talk and seen someone else come along and try to explain that it wasn't a real TED talk because it was a TEDx talk. Except on Hacker News, that person is usually just ignored. TEDx is substantially diluting the TED brand. Growth of TEDx has been far too fast and reckless.
