Unlike the Vine Society and Generation Twitter where everyone is dumbed down for expediency, TEDx prefer a longer format to communicate a larger idea, and with good reason. They imagine a world in which inept soundbites rule the day and despite all the chatter no real information comes out.
True enough, but I would also argue that because TED doesn't pay its speakers , it holds no value on ideas either. Except of course for monetization, since TED is more than happy to charge upwards of $6,000 a ticket for people to attend.
Nice try, TED.
