Have enjoyed two or three videos from these sites, and look forward to finding more new content on them in the future.
Fora.tv (Typinator keeps correcting it to 'For a tv' but it's Fora really) was something I stumbled on (from Lone Gunman) this morning. I watched this interview with Jonah Lehrer on his new book; bit brainish, but good if you've got the time (certainly some great stories in amongst the big sciency words).
The other site is TED, which I was pointed to a month or so ago, and more specifically this video about what wisdom is. Again, some cracking stories to illustrate the points made.
