I think mturk is vastly underdeveloped, there are all sorts of things people could be using it for, but don't simply because they don't know about it or it's too complex. Before I started my current startup, creating an mturk competitor was something I considered, but the fundamental problem is handling the payments. Most payment processors wouldn't touch you due to the risk of fraud without a huge (>1mm) deposit. Paying individuals small amount of money is hard, you pretty much have to use paypal, and if you're lucky enough not to have your account suspended they'll completely rip you on the charges. And you'll still carry all the risk of people trying to use your system for money laundering.
