Great businesses can be built on scale. I think Amazon has built a phenomenal commerce business largely on scale. Their network effect isn't obvious to me, but boy, have they used scale effectively.
I had a spectacular four years as OpenTable CEO and remain an active executive chairman. I think, for me, some of the interesting observations there are, you know, global is important, mobile is extremely important. And then, network businesses are very attractive.
I think if you look at the commonalities between eBay, PayPal and OpenTable, all three are businesses that built a network in a vertical. Network effect businesses are very attractive businesses.
Those are the main schools that are sending me stuff. So I just want to go out there and work on everything, since I know the players here are some of the best in the country. Just going out there and playing how I play will help my overall game. I don't worry about the rest.
