Last I checked, MTurk still accepted only US credit cards. This puts a dent in the potential size of the ecosystem.
If the purpose is dirt-cheap labor, they should open up the door to markets where $cents matter.

I'm pretty sure I recently used a non-US credit card to pay for MTurk. They require you live in the US, but they don't seem to verify that.
They verify for valid zip codes and they prune false addresses from time to time. You have to lie to Amazon, or know someone in the US.
I've used it a few times and because the eco system is truly about hiring dirt, dirt cheap labor you kind of get what you pay for.
Beyond that the revenue model sucks - the concept of running millions of micro-transactions and having a little piece of all the action is compelling, but again because the product use is so limited it's difficult to make signifigant revenue.
