I wonder if you can always turn a double-marketplace problem into a situation where the buyers and seller is the same person.<p>Or, if it means figuring out a way to change your business model to make sure they do become the same person.
That's a really going point but I wonder how true it is for Odesk. It would seem people on there are either looking for work or looking for workers. I've only been on 1 side of that equation.
