I just noticed that a lot of our tags here do not have any wikis/excerpts, and they seem like they're almost identical. Can someone please suggest how they're different and whether or not we should remove them or add descriptions? Perhaps some of them could be marked as synonyms too.
An excellent example of a question which looks like it has some really redundant tags is Are there guidelines for reopening questions? (v1; not edited by Qmechanic yet :P). I do not blame the OP, since those tags exist and obviously one would be compelled to use them, but I do feel that at that point, they're not helping accessibility: they're actually making it harder to find questions. For instance, if I have a certain question I'm trying to find, of if I want to look for "some" category (note that if there was a tag excerpt for the following tags, I'd know what to replace "some" with), I have no idea if I want close-reasons or closed-questions. IMO if you're talking about a closed question, you're almost inevitably going to discuss the reason why it's closed, and that would also pull in a subset of the scope tag. However, the scope tag is not present for a lot of these. Similarly, most of the questions in the vote-to-close tag are not technically about the mechanism of close votes: only this and this from the tag's first page appear to be appropriate.
Can we add tag excerpts to these and create a few synonyms? Preferably the creators would do that; I have no idea what those were created for, and the lists of questions underneath them does not really indicate what they're supposed to be categorizing. Hopefully the tag excerpts would contain some notes about where the tag could be used.
Once the superfluous ones are obliterated/turned into synonyms, and the surviving ones have excerpts/wikis, can I/we go on a tag editing spree for the last couple of weeks' questions? I see a lot of questions just on the front page which I suspect could use a fix of that kind, based on my slight guesses regarding the meanings of the tags. Or should we just leave the old ones and make sure that the new ones can be chosen well?
If they are indeed distinct tags, could someone post an answer regarding the differences? After that, can I/we go through the first page or so of that tag and remove it from the questions which don't need that, to ensure that the question list gives readers the correct impressions of the use of the tag?
Other redundant tags I've noticed: moderators/moderation*, review/review-tools, and duplicates/exact-duplicates (though there's a pending synonym suggestion for those two).
* This is a great example of a case which may seem like perfect synonyms based on the usual usage, but 'moderation' could theoretically refer to broader moderation activities by the community
