Okay, i stumbled across this site a while back - sort of a YouTube but chock full of interesting talks by influential people in their field of knowledge. Well worth checking out in my opinion. Something for everyone i think, as the T stands for technology; the e stands for entertainment; the d stands for design. Hope you find something on there that interests you!
Here's a link to Rob Hopkin's talk on the Transition movement he founded but if not your cup of tea there's all sorts of stuff on there! Hence the slogan "ideas worth spreading".
