I saw Jerry facilitate conversations on stage at a TfT one-day conf at Betaworks NYC, Gordan Brander had presented Noosphere too.
Jerry and his 2nd brain are seamless. It's kind of amazing to watch live. He's been at it for so long that there really is decades of connections at his fingertips and he uses the brain to deepen the conversation and the conversation to add to the brain, and he's able to do it without breaking presence/flow somehow.
