David,
First...here is the complete sentence.
If you randomly poll 485 professional developers and ask questions like "what languages/tools do you seriously work with", and "which languages do you think should have been on the list that weren't", you'll likely see results similar to theseAgain, I didn't say the site conducted a random poll. What I'm saying is that I strongly believe a random poll would likely yield similar results.
And the survey results shows the bias you'd expect based on the sampling of people that took the survey. How do you know that? We don't know how many used Fox (or other tools) in the past, but no longer.
But let's assume you're correct: if you went to a Fox user's group or some other Fox organization, you'd get Fox biases. Question: what (for you) would constitute a sampling that didn't have self-contained "biases".
T-SQL isn't on the list anywhere either so does that mean it's an "other end" (your term) language too? T-SQL is in a different category because of the specialization. T-SQL development has 2 general camps: DBAs, and application developers who work in at least one other language. T-SQL is tied to the database.
Might I suggest you google the two topics a) innumeracy and b) statistical analysis and read a few articles before you go making any more statistical pronouncements about computer languages? I studied statistics in school, and I've read "how to lie with statistics" - but thanks for the recommendation. Maybe you can attend an MSDN event and see how many are actively using Fox, as a % of the other tools mentioned?
