The main page claims "the ratings are based on the number of skilled engineers world-wide, courses and third party vendors" yet the definition page says that all they do is search for "$LANGUAGE programming" on a few sites and add up the hits. The sites are Google, YouTube, Wikipedia, Blogger, MSN, and Yahoo. None of these are particularly relevant to the industry and search results could be affected by a wide variety of factors. I don't see how any conclusive meaning can be derived from this methodology. I find it strange, for example, that Scala is not in the top 50 and Clojure is not in the top 100, while languages I've never heard of make the top 20.
