I've been wondering about tag overlap lately. For example:
soqlpost is about
query, but not the other way around
formula-fieldpost is about
formula, but not the other way around
before-triggerquestion is about
Should we retag new questions when we see a gap there? Surely tag synonyms are inappropriate here, but I'm wondering if it really makes sense to add the
query tag to
soql posts, and so on.
I'm not sure how much tagging matters to others here, but I know I find it makes the search process easier.
