My question is similar to this one
I just want to ask if I should remove a user's tag if it doesn't fit the question anymore.
I'll give an example.
User wanted to solve some problem with tool X, so he tagged a question with X tag. In the answer we found out that tool X is not suitable and problem can be solved with tool Y. I know that I can add Y tag. But can I also remove X tag? Maybe it would help other users that X tool is not suitable, but on the other hand, it could make things more transparent.
