Using Mechanical Turk

Some interesting movement out on the MTurk front: HNN post, Crowdforge (a framework for using MTurk effectively), and Soylent (a Word add-in for harnessing MTurk to improve documents).

Update 2013-1-1: Crowdforge, I now see, is released under a non-commercial license.  But it appears to have some kind of notion of workflow definition.  So it's interesting, but not sufficient.
