On the subject in the title: Request: a per-category review queue Working notes rather than a conclusion.
Nominating something for promotion into the documentation commons.
The topic in question keeps being re-asked, has a good marked solution, and contains a worked example that would be more useful on a page with a review date than buried in a reply. That is exactly the promotion criterion as written.
Objections welcome and genuinely wanted — the whole point of discussing promotions in public is that a bad promotion is harder to undo than a bad reply.
