I'm currently looking at this question for my own projects ;-) When it comes to a job, I care less about absolute productivity and more about relative productivity, salary, people, culture, location (not in that order). But when it's me, myself and I, then focusing on having a language that I can be amazingly productive in becomes a much bigger priority. I remember Paul Graham once writing an article on how he build a search engine company and was so much faster because he decided to use Lisp instead of C. In terms of productivity, I'd like to see if I can replicate that, at least a bit.
