I have posted some queries related to bounties on MathOverflow Meta: What would be good place to list unresolved bounties?

Although not something about bounties which haven't been awarded - so now I mentioned your query at least in a comment.

@Martin why don't you add it to the answer?

Well, MO users are more grumpy about bumping than other sites. (At least among those sites that I've seen.)

Ha, okay. That is something you only know if you're a regular there.

No need to make people grumpy

Well, at least that's my impression of MO. (Others might see the site differently.)

This feature request was linked in several other posts: Minor edits, subject to review.

Yeah, that is a known debate, not only on MO.
