I read through the analysis and it sounds off. It assumes that the number of people interested in JavaScript correlates with the number of searches for "javascript tutorial". This is incorrect. Many people search for "nodejs tutorial" or other variations. There might be a growth in "nodejs tutorial" searches at the expense of "javascript tutorial" searches. Similarly he does not see an increase in searches for "objective-c tutorial" and assumes the language is in decline. In reality there might be growth in terms like "ios tutorial" or "iphone sdk tutorial" which his metrics don't track.
