Justin, my apologies on that, I misread the screen and thought I only got 104 answers.
It was a great experience overall, and for micro-testing (where something like Usability testing is too much) PickFu is on my short list for future projects.
Thank you for doing this. Living outside of the US means that I cannot use the Amazon Mechanical Turk. I just launched a $17 test. If it works well, I'll use it again in the future.
I spent about $20 to get 200 responses for my question, but only ended up collecting 103 answers before the question expired.
None of this stuff is perfect, but employing a few of these approaches all at the same time will generate results that can be handy to correlate.
