This question How fundamental is undecidability? was closed within 25 minutes of being asked. The OP was rude to a moderator in the comments, and it isn't a great question, so I do think closing it was a fair call.
However, for me this has highlighted that we seem to be closing questions rather quickly, and certainly before the OP has a chance to change the question in light of comments, for instance to add pointers to literature, or to explain their motivation.
This may be a reasonable rule, but I don't see it in the FAQ. Some poor questions in the earlier days of the site went on to be revised (by the OP and by others) to become interesting and useful, generating significant numbers of page views and votes. There were even instances where for initially uninteresting questions some great answers were provided (e.g. Highest lower bound on NP problems (TSP), True Bit Complexity of matrix multiplication is $O(n^{4})$, and Permanents - Approximation and connection to integer factorization come to mind). I don't have easy access to the vote histories for pages, but I seem to recall that some fairly anodyne questions even ended up being heavily upvoted after a stellar answer was provided, sort of basking in the reflected glow.
Previous discussions mentioned wanting to keep a clean front page during the beta, see On closing, and the awesome power of moderation, How Much Time before Closing a Question?, and Why the extreme strictness on topic closing?.
I would even hesitate asking a question like Rigour leading to insight today. This question started out quite vague but through feedback turned into a reasonable question, and more importantly led to insightful responses by several people.
Is there an unwritten rule that no-one (not even Ryan) shall ever receive the reversal badge?
