Is questions asked really a good metric? StackOverflow actively discourages asking duplicate questions, and all the easy newbie questions haven't changed in a while, it seems inevitable that certain technologies appear to decline. This is addressed in the article. There have been 1.4 million javascript questions asked and the pace is increasing, which indicates that it's hard to exhaust a subject. I think it makes sense facebook api usage is in decline given that the game devs have moved away from it. I also don't think days a vacancy is open is a good metric, because having been on the hiring side of trying to find Delphi developers I can assure you it is very tough. Plenty of people have relevant experience, but none of them want those jobs because they think it is career suicide.
