Despite my best efforts, there was no way that I was going to actually manage to blog while I was still at the TED conference this year. I don't know how anyone can do it. I suppose that is why there was such an explosion of tweeting at TED - you can do it on the fly. But if you want to sit down and write anything vaguely coherent, it takes time. And the TED conference isn't about free time. In fact, I managed to get about 10 hours of sleep over the last three nights of TED.
