Celebrating the second year of sharing videos of talks from the annual TED conference (still waiting for my scholarship :-), the people running the site have posted a selection of the ten most popular.
I could quibble with a few of the choices but not with the fact that all are excellent, especially my favorites by Ken Robinson, Al Gore, Hans Rosling, and Tony Robbins.
While the highlight reel is fun, go watch all ten. It will be well worth your time.
BTW, you can also subscribe to the videos in iTunes and take them to go.
