I think there are significant problems with this approach which you have not thought through. First, I believe this kind of market devalues programmers and programs. It takes a whole lot of small transactions for a programmer to make a living in this kind of market. Second, it's not really useful for anything other than trivial programs. Getting agreement on a reasonable specification for anything at all complicated takes time, and for the programmer in this space, time is money. Third, What happens when there are multiple responses to a question--does only one responder get paid, or do all get paid. Fourth, there is no effective mechanism for quality control. Who has the liability about quality? How is testing conducted? Fifth, who owns the code? who owns the copyright on the code? Can the code be redistributed to others?
