A few quick notes before I run into the next session:
One of the best TED-U sessions was Derek Sivers on what it takes to be a leader, with a shirtless dancing guy as the news hook. Treat yourself to this three-minute talk.
I wrote about Jamie Oliver's TED Prize talk on Wednesday night. See his talk (below) and read Garr Reynolds' trenchant commentary.
And, finally, do you want to give a TED talk? The guy who decides whether you will has advice.
