Tiobe can easily be gamed. Look at OReilly's book sales to see a truer ranking of language popularity at http://radar.oreilly.com/2012/04/computer-book-market-2011-part4.html http://radar.oreilly.com/2012/04/computer-book-market-2011-p... The treemap is especially interesting. The square size shows market size, while the background color shows percentage change from previous year. E.g. both Scala and Clojure have green "increasing share" squares, while nearby Groovy and Labview have smaller, red "decreasing share" squares. Because people need to pay OReilly for the book, it's much more difficult to cheat than Tiobe, which only takes some "Project Manager" to spend half their day creating websites, generating cycles of links, producing online verbiage, submitting pages to search engines, blah blah blah
