Ask HN: Who is Hiring? (February 2012)
I'm sure this has been done but out of curiosity I wrote a (highly unscientific) little script to count the times that some languages are mentioned herein[1].  The results:    java: 53
    python: 28
    ruby: 16
    php: 14
    node: 9

Winnah: Java! :)EDIT: Thank you goo!
Take 2, maybe it will work better:    java: 42
    python: 38
    javascript: 34
    ruby: 24
    php: 16
    node: 15
