I've just been doing a bit of tags clean-up (a bit of retagging to the correct subject tag, and a bit of merging and deleting). (Incidentally, it'd be great if more people keep an eye on the newly created tag list. You can see it by going to https://math.stackexchange.com/tags and clicking on the tab for 'New'. Some of the ones I just dealt with were pretty far off.)
A request and a question:
- There are a few tags dealing with subjects that I am not expert in (various things related to abstract-algebra, graph-theory, and such), it'd be great if someone more expert can check to see if the tags are applied correctly and if those tags are actually necessary. (Tags that are too specific and tags that almost surely will duplicate key-phrases in the text/title of the questions are generally unnecessary.) (You can post suggestions for mergers at Tag merging and synonyms .)
- What should we do with tags for questions that are very off-topic? For example, there is one question currently tagged tex, which really better belongs on the TeX StackExchange (my question is not about this particular question specifically, but about a general scenario that I will outline in a minute). But the tag is a reasonable description of what the question concerns. So:
Suppose a question sports an accurate but off-topic tag, and the question was closed/migrated. What should we do with the tag?
