I've noticed that every time somebody poses a question along the lines of "What are some programs other coders find useful that I might not know about?", it is, no matter how many upvotes or answers it gets, doomed to closure.
Why? We're programmers; the computer is one of our most crucial tools. I would think that a question about making more efficient use of your computer would be extremely relevant on a site dedicated to programming. And based on the kind of response and participation the best of those questions tend to get, I'm not the only one.
(Disclosure: Yes, this was prompted by a question I asked on this subject getting deleted. And yes, that rankles. But it was a useful question -- and I've noticed that the topic seems to provoke a whack-a-mole reflex from the moderators in general. I honestly want to know why.)
