I've made this point a few times here on HN. StackOverflow QA& isn't really a good indicator of anything industry wide. Most experienced developers who know their language just use API docs if needed to get things done. Sure there might be some obscure edge scenario you need to ask a question about once in a while. Beginners ask lots of questions also new languages/frameworks will generate interest and questions. That doesn't mean those are the things that are most used or most in demand in the industry. Also SO primarly contains questions on open source based web programming. This discounts entire sectors of the industry using proprietary tech. SO likes to publish their metrics since it brings more attention to them, its marketing, they are a business. A good way to track things would be if job postings (not just SO careers) could somehow be marked as filled. Then you could ascertain from the description what tech stack is used.
