I've noticed a common pattern among new users to use the abstract-algebra tag, often times when the question has little to nothing to do with abstract algebra. I recognize that mis-tagging is an easy mistake to make for a newer user, because they don't really understand the necessity of choosing the right tag, and sometimes they simply don't know what subject their question would fall under. But abstract-algebra seems to be a top choice for new users as a mis-tag. Here are just a few examples:
I suspect it may be that users are thinking of the subjective meaning of the word abstract, feel that their algebra question is sufficiently "abstract" to warrant the tag, but aren't aware that abstract algebra refers to a specific field of mathematics. In that case, it may be helpful to edit the tag excerpt in order to clarify not to use the tag unless the question is about the algebraic structure of rings, groups, fields, etc. I've seen a similar thing done on tags on other sites, like the glitch tag on the gaming site.
Has anyone else experienced this pattern? Does anyone else have any thoughts on this?
