The whole basis of stack overflow is asking questions about things you don't know or understand and mostly about open source software. "Tracking interest in programming languages and technologies" based on that premise means that the results will be flawed if you think they represent all of software development. Popular items on a Q&A site are going to tend toward things that are newish or are churning through releases where things are changing rapidly. jQuery is trending down and angular is trending up very quickly... does that mean angular has more interest? Or does that mean that most jQuery questions already have answers? It would be interesting if there was a general curve of Q&A about software tech to compare against. A control group if you will. Then you could see if something was growing faster than the control group.
