I recently had my edit suggestion rejected when I tried to add a tag to someone else's post. I grant that my new tag didn't "help to define the topic of the question," (The body of the post itself does this quite well most of the time, and I confess I didn't even know this was a purpose of tagging.) but should I really not add an appropriate tag that would increase the visibility of a good question to people who can answer it? This seems odd but I trust there's a good reason for it.

For context, I tried to add differential-geometry to this post One parameter subgroup that leaves every compact set is a proper map

  • $\begingroup$ There will always be edge cases, at least for most rules. You want "to increase visibility", so put yourself in the mind of someone who searches for that tag: Is the tagged Question going to be signal or noise? So the dictum in the rejection template singles out the issue of whether the tagged topic "describe[s] what the question is about, not just what it contains". $\endgroup$

Your suggested edit was good. The review system is not perfect; nothing is. In particular, tag-only edits tend to be judged more harshly than other edits.

I added the tag.
