The comparison tag has 121 questions, almost half of which have zero upvotes and only one of which has a score >10. There is no tag wiki or usage guidance.
A substantial proportion of statistical questions involve some sort of comparison, so this vague tag doesn't seem to serve much purpose. A quick skim through some of the tagged questions also suggests that they would be better served by more specific tags.
Shall we delete this? And is this something that the mods can do at the site level, or does it involve manually removing the tag from each of the questions?
