why? What's good for MTC is also good for Bezos. People make some money on MTC, requesters have to post hits for MTC and others to make money so Bezos gets paid for listing those hits, handling the payments, and (I suspect based on doing some of them...) money for using AWS to host some of those hits.
I have to check the Amazon annual report - the stock proxy came the other day, I've voted, but I haven't looked yet in the accompanying Annual Report to see if AMT is listed specifically in the report and if there is a figure about the number of registered or active turk workers (doubtful as its probably proprietary) and how much revenue and expenses there is for the AMT portion of Amazon.
