Really interesting... thanks for sharing! For our surveys, we also captured specific demographic information to get the most representative sample as possible.
@hansef - this was (is?) definitely my impression. But turns out mTurk users, on average, are more educated than the average population. Many in business roles. We were surprised by some of the responses, and indeed the b2b profiles on some of our profiles. I guess like everything startup, worth testing and challenging assumptions.
At the price point for interviews and with the ability to validate, it's worth a try. Using the guide, it can't take more than 1 hour to set this up... faster and cheaper then getting assets up and ready on FB.
Really great post with 2 super relevant examples to interview and test the theories that make up your business. I'm curious how other people are using mTurk (and other scalable solutions) to help test their theories. Any winning ideas out there?
