There’s a now-famous interview with Mark Zuckerberg, back when he was building what he called “TheFacebook.com,” in which he’s very passionate about his idea, but also not very clear about it. In a traditional business setting, people wouldn’t have invested in his idea after listening to his description. He said, “I really just want to create a really cool college directory product that is very relevant for students. I don’t know what that is.”17 But startup culture made it possible for investors to take him seriously, and it gave him a chance to experiment with his idea.
