If you are interested in mturk I'd suggest trying out A9 Data Collection if you have an android phone. It's hits you complete by taking pictures of whatever they require. Mostly household stuff like tools or clothing or even office supplies. $.07 per picture with 5 pictures per hit allowed. Doesn't sound like much but it helps rack up your completed hits. Good way to keep going if you can't be sitting working on a survey or something.
I do it at work were I never have enough time to do surveys but snapping a few pictures is a breeze.
> A9 Data Collection in the Play store. Not sure about iOS but I'm sure a search would pop it up.
It is only an Android app. https://play.google.com/store/apps/details?id=com.a9.datacollection.mturk
They've been running these for ~6-8 months now.
