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)
This talk is not about hallucinogenic mushrooms. It really opened my eyes to the awesome potential of fungi, and how this potential is largely ignored because of the connotation to "hippy" and "drugs." Fungi is just generally misunderstood. I was absolutely amazed at how thorough these clean-up jobs were, at how well the fungi consumed, not only the waste, but the toxins in the waste.
