I've been going through the thread from about a year and a half ago that has a myriad of great TED talks, watching one or two of them every few nights. (http://news.ycombinator.com/item?id=442022)
I'm starting to run out on that thread, and I'd love to get a good compilation going that includes some from the past 2 conferences.
So, HN - what are you favorite TED talks? I'll get it started with these: Sir Ken's Robinson's talk on nurturing creativity in education (http://www.ted.com/index.php/talks/ken_robinson_says_schools_kill_creativity.html) and Inspiring Action through leadership (http://www.ted.com/talks/simon_sinek_how_great_leaders_inspire_action.html)
