At some point we should be creating tag synonyms, as soon as we have users with enough reputation or some pro-temp moderators. We should start to collect possible synonyms and discuss them.
If you have an idea on a synonym or want to rename a tag to something better, please put your proposal in one answer to this question. Please add also a short justification for the synonym.
Please upvote synonym- or renaming proposals that you agree with and downvote proposals you disagree with.
