TED and TEDx had great content in the first few years, when profs were able to present their lifetime's work.
Once they burned through those folks, they turned to cranks/homeopaths/etc

Though from a public speaking point of view, it's well worth studying (both actual TED talks and this satire) to help make legitimate talks more polished. There's an exchange of emotions that goes on during great talks, and that really helps drive home points.
Once these talks became more about the delivery style than actual substance, it kinda devalued the whole TED branding.
TED talks were never the best source of information, but at least they weren't actively misleading.
ted-X on the other hand.....
