"Has Your Head Exploded Yet?" BoomTown Queries TEDsters on What They Learned

While at the TED conference last week, I asked a variety of people in attendance at the elite gathering which presentation had blown their head off–figuratively, of course! TED, which feels like a four-year college in four days, had an eclectic range of speakers, many focusing on the awful state of the earth. But there were also less-dire presentations, such as one on how Brad Pitt’s head and range of facial expressions are now stored in a Sony database for all eternity. That’s a cold comfort amid all the global melting down, but BoomTown will not refuse it. Here’s some more TED reaction from the digerati.
