Another talk from yesterday worth checking out was Bill Gates' talk on the work of his Foundation. He gracefully handled the fact that he was in the Rebooting section, attributing it to the rebooting of his career, now full time at the Foundation. The first of his annual letters is now available at gatesfoundation.org and is worth reading for its thoughtful discussion of significant problems, why they picked the ones they did to work on and progress.
At TED, he talked about two of those priorities, fighting malaria, and improving American schools. That talk is already up at ted.com. You'll love the question period, when Chris Anderson pulls over his computer to read off some questions sent in from the Web and is oblivious to the fact that he's just set the glowing Apple in the foreground of the rest of their discussion! The audience chuckles you hear is because the audience was fully aware of the irony!
