For example, if someone asks this question:

I'm getting an error doing X. Why?

A possible answer could be:

You need to do Y to avoid getting this error.

If Y is a technique or tool and if Y has a tag, should I edit the question to add the tag? It seems correct because specialists in will be able to find the question and add more useful information.

However, I can see two issues:

  1. If or is also a possible solution, the question will have many distinct tags.



My PC is freezing. What should I do?

Answer 1:

You need to run an anti-virus to remove malwares.

Answer 2:

Your PC may be overheated. Check if your fan is working correctly.

So, in this case, should I add + to the question?

  1. If the question is marked with , the OP will look a bit dumb for asking something that is quite obvious if you see the tag.



What series is it?


This is "Game of Thrones".

Adding a tag would make the OP to look dumb.

Another example for this would be:


How can I securely store an user password?


You should hash the password before storing it.

In this case, should I add the tag?

So, how should I proceed? Is there a generic guidance?

    I was always under the impression that tags should be based on the question, not the answer... that question goes against that concept entirely.

    I prefer to see tags that represent the Q&A rather than just the question that it can be considered the evolution of. I think it is fine to add tags that result from accepted and/or highly upvoted answers because they will help answers to be found by later searches.
