I think there are going to be different kinds of users and different kinds of task publishers. Each will utilize different motivations around what they do. We are working on a way to allow this. I think that payments are good, but there's also coupons/offers, gamification or social standing, participatory privilege, etc.

I worry that if we do micropayments for microtasks we'll end up in a very specific pigeonhole that isn't insanely interesting.
