I was thinking more along the lines of something very simple and very free, since I have minimal computer skills and financial resources. I have SPSS for analysis, so all I need is a form that collects responses and sticks them into a spreadsheet. One of my friends helped me do a survey before, and I was planning to pester him until he showed me how to set something up.

If you're a professional, though, I defer to you if you want to do the Unofficial Less Wrong Survey instead. Or if you want to cooperate on it, email me at yvain314@hotmail.com. If not, no worries; I'm sure I can set something up eventually.
