I seems somehow implausible that Javascript is so low given: a) The amount of "Web 2.0" applications that are being developed. b) The number of OS/Windowing systems that are supporting Javascript as a scripting/application language. c) The (almost) constant necessity of "tweaking" almost any web design at least slightly (using Javascript). d) The number of ready-made libraries to make programming in Javascript more fun. e) NodeJS (Do I need to say anything else?). I'm not a giant Javascript proponent, though I use it where it fits. But this "survey" seems to have a pretty significant amount of sample bias.
