I wish I remembered the person's name, but there is a guy in London who did a start up and made a fair amount of money. Since then he spends his time talking with different people to get ideas. He'll buy you a hamburger (at one of the upscale hamburger places no less) to talk to you for an hour. I never ended up chatting with him (I got busy), but a friend of mine did and said that it was quite a good experience. I thought this article might have been about that guy. It's a bit different, though. The person I'm thinking about is independently wealthy and thinks this is a productive use of his time. I think he's gathering data for a new startup, but unfortunately I didn't get a chance to talk to him about it.
