I found another (very simple) graph reflecting the rating of programming languages. Everything is elementary: horizontally - the number of projects on
Github , vertically - the number of questions on
Stackoverflow .

I allowed myself to draw two red diagonal lines on this graph to show how the mainstream (C ++, C #, Java, PHP, Javascript, etc.), the group of "alternative worldview" (Scala, Haskell, Erlang, Prolog, Lisp) and frank thrash (everything below). In my opinion, there is no place easier. There are no annual fluctuations of one and a half per cent, calculated using incomprehensible formulas.

UPD : sorry for the mini-trolling with the word "thrash" - but it gave rise to a very interesting discussion in the comments. All expressed - thanks.
