It strikes me that the number of times tutorials are sought out via Google may be indicating something other than "popularity". It seems more likely that an enormous number of Google searches for a language tutorial may be an indication of 1) how difficult the language is to master i.e. those using it are having to refer to tutorials far more frequently than more intuitive languages and/or 2) how few learning resources exist for the language.

I mean, developers may not be doing Google searches on say VB.NET tutorials because Microsoft makes it so easy to find resources.


it makes sense to choose a language for each situation based on what fits best with the requirements, needs, people, resources and objectives of  situation. "Popularity" is a subjective term that is largely meaningless in a discussion of language-use metrics.
