I always get the feeling when reading about Mechanical Turk that for a service which promises the ability to get arbitrary amounts of lumpen labor for pennies with an API you have to do an awful lot of speaking to individually identifiable people about pennies, which is so far from my desired job description it isn't even funny.

(The attraction for me when I used FeedbackArmy was that they took care of the "managing turkers" headache for me. I boggle that someone would want to do that, but I guess people boggle about my business model, too...)
