Biased towards users of StackOverflow, not developers in general. Unless you believe the population of developers who took the survey is representative of the entire world of software developers--I'd be willing to bet it's not.

Yep, StackOverflow tends to be a ghost town on non-web-related technologies, and basic programming language contructs/techniques - and those are heavily weighted towards Ruby/Java/C#/Python, where the questions are not necessarily about web dev, but you can tell the questioner is working on the back-end of a web app.
