I think Amazon's Mechanical Turk (MT) is fascinating. I really wish Amazon would release more figures on its usage, rather than only the number of registered users[1].

It would be really interesting to see how many people earn their wages through this service. The chart in the article says 16% in Feb '10 [2], but I think it would be really interesting to see 1) how much money they earn, 2) how many hours they work, 3) where they live, 4) how much Amazon pays out in total in MT wages (all anonymized data, of course).
