 So Ted, viewed one way, is there to celebrate a really, really weird human ability. It's this ability to hold the world in your head or a piece of the world in your head and play with it and tweak it and reposition it until you come up in your mind with a better world. We sometimes call that invention or innovation or imagination, but really it's design. That's what it is. So we have a conference, which for whatever reason people seem to get excited by. And I think it's because of that because you spend days immersed with people who can do that really well, who can excite you with their re-imagination of the future. For years now we've been following what we've called our philosophy of radical openness and that began with Chris's decision to really open the conference up to the world and has really become a several year long experiment in what openness can do to an organization and to the ideas themselves. And so everything that we've done since really over the last eight to ten years has been to figuring out how can we open ourselves up more, how can we allow our community to build with us, which is a really kind of fascinating design challenge for our time.
