Unless you know that language best and deliver the best results in it. I used to always be completely technology-agnostic, until I realized that not everyone has time to learn the best technology for the job (unless your company is filthy rich with talent). A coworker of mine was preaching "you can't just go with what you know" the other day, and I thought to myself, "hold on, that may be good and PC, but if I'm the head developer on this project, and I'm not using anything too exotic, why not, assuming that the app is stable and can be reasonably supported?" I know that when I work with other developers, I want them to use what they will do best with, because I know that I and others are more than smart enough to make minor changes without breaking the thing. Now, it better be well documented, but that's another matter... Edit: And dammit, why does this topic title tempt me so much to say "your mom is implemented in Lisp"? That's gotta mean something, and I'll bet it's cold as ice.
