I am extremely intested in online economies that could emerge. It seems like somehow if the open source initiatives or wikipedia somehow involved micropayments people could be paid for very small increments of effort. For example someone could sit down from a third world country and earn some money by doing some creative work.This could be all online. I have visited Second Life.com and they allow people in this virtual world to sell their virtual products in real money. Just wondering if more of this could be done and the effect that could have.
