Here is an "Advice" question, In Common Lisp, replacing "get-setf-method" with "get-setf-expansion" is not always working, that should have been a regular question. The question poster meant to post as a regular question, but misunderstood the UI and mistakenly chose "General Advice/Other".
Aside from maybe making sure that the UI is clear and understandable, it seems like there should be two mechanisms to prevent content that should be posted as ordinary questions from being posted as opinion-based questions. One mechanism that allows a poster to revise the type of a question (perhaps in some grace period), and one voting/review mechanism that allows the community to revise the type of a question.
Or consider this "Best Practices" question that 1) has a clear and objective answer, and 2) has at least one obvious duplicate and probably a few others (I seem to remember seeing another dupe of this question just a few weeks ago).
The question can't be flagged as a duplicate because the UI doesn't allow it. The question should be a regular question, anyway. "Best Practices" is a terrible and confusing category, and often such questions are easily objectively answerable, as in this case.
Further, the poster of this "Best Practices" question has gone on to post further questions in the "Replies" section below. My understanding is that "Replies" are intended for answer-ish content, not question-ish expansion, yet there is no way to flag a reply for deletion without bothering a moderator directly.
