Hello h Bar: Perhaps you can help develop a half-baked idea of mine. A handful of tags are prone to misuse and overuse, most notoriously perhaps the
mathematical-physics tag. Idea: "Protect", say, the
mathematical-physics+ tag with, say, a plus in the end. (I put the word "protect" in quotation since there are no actual reputation restrictions on the use of tags.) All appropriate mathematical-physics question should be tagged with this new "protected plus" tag.
