This never got off the ground.
CoinWorker isn't really similar to what I had in mind though.
please explain the difference of what you are proposing (vs. coinworker) and why I should use it rather than coinworker...
Read the specs I linked to.
CoinWorker is for limited, very specific tasks.
I'm thinking of a buyer-oriented site, where individuals could create tasks suited for them (different skill levels / tags / price ranges).
fiverr/mech turk don't fit this bill:
fiverr - focus on task sellers (will do X for $5), focus on tasks in with specific price tag. Huge commission btw (20%!)
mech turk - focus on presenting one task to a lot of people (I need 100 people to review this png and look for irregularities).
