I'm not sure how many of you are familiar with XKCDs color survey that was up awhile back, you can read about it in his blog, but I want to have a test along the same lines as his. Ask some questions and collect people's responses. Not necessarily about colors and such. I want to gear my test towards converting emotions to numbers using the Plutchik wheel of emotions. It would simply display a word and the most generic picture I can find depicting that word and have nine inputs, one for each emotion on the wheel and one for a explanation if the user wants to leave one. I haven't decided what kind of inputs, textboxes would offer usability, but dropdowns would better restrict user input to valid data types. No code has been written yet, still in the planning phases.
In short, how can I implement the survey in the best way to let real users take it and still be able to weed out spammers.
Note that this will probably end up being written in PHP, but if ASP.Net contains better features for it, that's a possibility, too.
