The online company Helium is trying to create a sort of peer-review writing/editorial virtual space for freelancers. I have 0 time to explore this at the moment past browsing the model, but it is _really_ cool. It operates on input metrics – you have to write in order to be able to rate. Ultimately, the best writers are supposed to be the ones who get the cash.
I am curious to see how this pans out.
