What is a Polyglot programmer? A programmer who speaks more than his native language (e.g., for me it's German, English, Chinese)? A programmer who codes in more than one language?
See here http://www.techrepublic.com/article/developers-are-calling-i... for instance

Basically the big G is your friend?
I don't think we needed an example in order to understand "speaks more than his native language".
