There are several helpful and thoughtful comments. There are no close votes, but two down votes appeared quickly.
Below them I wrote:
'll bet there can actually be an informative and authoritative and well-received answer post to this question - but I'm tired of the answers in comments and down votes, so the community will now be deprived of the answer post because I'm deleting the question.
Down votes have several real effects. They often come from folks who don't really bother to generate many question posts (a Stack Exchange size is essentially a null set (as opposed to an empty set) without questions! cf. uhoh's lemmas) so they don't have the same awareness of the full spectrum of their impact that someone who asks questions would.
