I know a fellow offering a
free airplane ticket to anyone who persuades him. Just convince him you should get the ticket, and done. So far, all the reasons he's received are poor enough that he's holding on to it. This is a contest with no direct dollar motive. Maybe he's altruistic, maybe it's fun, maybe he's trying to draw attention. Anyway, surely there are people out there with a desire for that ticket who are so creative or with such interesting circumstances they'd have him fedex-ing it at his own expense.
However, he can't reach them just by offering the ticket. Probably he should find the places where creative people will see his offer, maybe Craigslist, Reddit, Digg, and so on. He actually will have to do work to give it away! Sound familiar, Internet startups?
