MathOverflow has a few problematic tags which are not inappropriate by themselves but suggest off-topic ideas. A prime example of this is the calculus tag. Sometimes a research-level mathematics question does involve some calculus so it is not inappropriate to tag such questions in this way. However — and very clearly so — not all calculus questions are research level!

Should MathOverflow:

1. Eliminate the calculus tag.
2. Keep the calculus tag but carefully pay attention to its usage.
3. Keep the calculus tag.

The ideal solution is option 2 but this is simply not feasible. In this case, option 1 is perhaps the best solution but what about less obvious cases like linear-algebra?

(If you think of a similarly litigious tag, please post an answer similar to the calculus model below so it can be debated separately.)
