It seems that among users who voted to reopen were some high-rep users. See revision history and review.
I know that it should not matter too much who voted, but still I view somewhat differently votes by experienced users, who spent some amount of time at the site and know (at least in theory) quite a lot about how the site works.
As much as I'd like to see great answers to this question, it's both too broad and opinion-based. What does "surprising" mean? The answer about Borsuk-Ulam doesn't look very "surprising" IMO.
Given the two related questions I already posted I highly doubt there will be completely new answers that weren't already posted there, or could be posted there.
Since this question was already closed, reopened and now closed again, I wonder whether it will get to review queue. I see it neither in history nor was I offered to review that particular closed vote.
@MartinSleziak So now that Daniel Fischer voted to close the question, is it too broad? I apologise if I overstepped my middling reputation to suggest that the question is too broad.
If this question is to remain open, I think it should be marked CW. I flagged for this earlier, but it was declined; probably because the mod taking care of the flag, Arthur, just closed it again.
@MikeMiller Actually, if you check your flag history the flag was marked helpful (ie., not declined). I just felt it was better off closed than CW. I'm not inclined to mark it CW. Maybe another mod will.
@ArthurFischer Sorry, I misspoke. Call it a thinko. I meant to say that it was marked helpful, but the mod taking care of the flag declined to mark the question as CW. Also, the last bit in that sentence should read 'just closed it instead'.
@MikeMiller But, but... there's so many gems in there! For example, "If you shoot $n$ pigeons with $m>n$ bullets, and never miss, there is at least one pigeon with more than one hole." Link
:P
I think some of the massively upvoted ones should be locked as "Preserved for historical significance, but no longer considered a good, on-topic question for this site."
> But if enough people (currently 3) select "Do Not Close" within the review queue, the question will be immediately removed from the queue (not shown to any more reviewers) and the aging starts immediately. -- Shog9
(They renamed the button since then, but presumably this did not change the functionality)
@MikeMiller Voted too broad. "Why do people ask 'why' questions?" -- For reasons.
