We've had a few discussions lately about proper use of tags on SGE:
All are based off of the same concepts:
I would like to clean up (delete/merge/rename) tags and bring more order to the chaos. What would be helpful to me is a view where I can see tags that have been used on many questions but aren't followed by many people. Adding this as another view on the tabs view would be convenient.
The threshold is debatable, of course, and should be based on the average number of followers on a tag.
In addition, I'd like to see a reverse view of the 'popular' tag listing. In other words, a view where I see the least-used tags that aren't synonyms for established tags.
I realize that the idea solution is to solve the problem of how people tag, and I do think we should have mechanisms in place to educate new users (maybe a listing of rules near the tags field). However, I think regular maintenance is going to prove necessary to keep tags in a healthy state, and this would help with such maintenance.
