Wow, that's a very good talk. He's a bit of a bleeding heart, but in such a way, that it's clear to me he couldn't be as effective as he is if he wasn't. There is also a lot of implication on what makes a good talk here. Thanks.
I love Jamie Oliver and highly recommend his show Food Revolution. It's 100x more moving than his talk.
(just tried to find it on Hulu and it's not there, wish I could provide a DL)
