Both the tags rankings and user-rank seem to describe the same thing as either top-users or reputation-leagues.
Since the tags pertain to approximately the same concept I think they should be considered together!
Currently:
reputation-leagues has 265 questions, has an outdated wiki by today's standards. It would be better served by writing a new wiki taking from the rankings wiki and focusing it exclusively on the leagues page.
top-users has 98 questions. Has a good wiki that should be focused and contain a link to reputation-leagues. It should be focused to be about all the ranking's questions except those of the reputation-league.
rankings has 39 questions, has a good tag wiki. However, most questions on the tag are not about the reputation-leagues page but are about the top-user (top-users) list of the tag pages.
user-rank has 19 questions, has no tag wiki. All the questions on the tag are about reputation-leagues.
Action that could be taken:
The synonyms page has no hits for the word "rank" and in the tags page there are only 2 hits for the word "rank", those are rankings and rankings.
Since the word "rank" is intuitive these tags should be made synonyms to keep the results in both the tags and synonyms page's search.
The most seamless solution would likely be:
- Synonymize user-rank -> reputation-leagues
- Synonymize rankings -> top-users
This solution would require almost no retags, but I somehow think the wording of user-rank would make a better fit to top-users and the wording of rankings would make a better fit for reputation-leagues. (I don't know if the tooling allows this switch.)
