I've answered a bunch of narrow questions like the ones you described, only to see them closed later because the community decided it doesn't want to include those questions. My attitude has always been, "Speak for yourself. I'm fine answering them." But, of course, they still get closed, so now I don't even bother.

There are people (like me) willing to kill some time solving useful problems that people in the real world are actually having, but SO's theory of broken windows is so extreme that they want to make me feel bad for doing that.
