The turk is so rarely updated there is probably some kind of disruptive startup opening for someone to set up a middleman service paying an hourly wage to carefully tracked humans.
This might put a stop to the horrible turk habit of claiming a 20 minute survey only takes 2 minutes or writing some kids term paper only takes 30 minutes, which is technically true if you spend no time thinking about it and can type at 250 WPM, but for almost everyone else its a bit unrealistic.
Some communities have sprung up on reddit to highlite great HITs but they're very realtime and seems like as soon as a great HIT is posted to the reddit group, in seconds its gone, used up. A better marketplace dynamic could be set up. Clearly HITs and turkers are not really commodites after all in practice, so commodity market tools do fail. Tools that better match the market would be better for all participants, and the market maker skimming off the top, so its mystifying why they put no effort into it.
