I had to come up with 111 business ideas for Seth's alternative-mba program this week. The idea was both to make sure we weren't choosing the business we wanted to start just because it was the first good idea we came up with, and also to prove that ideas were worthless because we could come up with a million billion-dollar ideas. There are nine of us, and so that's 999 ideas between us. We are going to take the best of these ideas and publish them all online. Of the 150 or so ideas we publish online, I suspect that 145 or so will be done by someone within the next five years. It's not that uncommon, it's just that everyone tends to think of the same stuff at the same time. That's why hit movies come in pairs.
