At first I was about to dismiss this as TIOBE-like crap. But giving it a second thought, there is a deep difference in methodology. TIOBE - language is popular if "<language> tutorial" brings up lots of results on Google This page - language is popular if many people searched "<language> tutorial". It's not hard to see that the second one is a much more interesting metric. That said, it's still far from being enough to evaluate a language's popularity. On the other hand, it can be at least mildly correlated with the amount of people wanting to learn said language over the measured period of time.
