Often when users, mostly new (those who get association bonuses) ask a question, to identify it or its basis they will often create new tags and leave them as just that.
For others of us who have no idea what this is, might want to help or are just interested it should be there. This also creates a plethora of cryptic tags that are either localized, vague or useless.
I propose implementing a way of encouraging people to document any new tags they create.
How can we prod users to document tags or encourage them to use related ones or at least limit the number of additional tags on a question?
Eg. I saw donyatsu this morning and was intrigued but it wasn't until after several google searches I was finally able to put a synopsis to it.
