In this question, after the story had been identified someone added the tag of the correct answer to the question.
This story-identification did not have a title OR author attached originally. The author was not in the new tags, just the story title. It is not the same question.
I don't see the point of adding the correct answer tag in an identify-this question after-the-fact. Sometimes I search by tag and if something like this popped up it wouldn't seem to add anything to the information base or help with any knowledge or trivia I'd be potentially seeking (other than someone didn't know what it was). I was going to vote against it, but took too long thinking about it and it was voted through.
Are there any benefits for this edit? Does anyone have an example of how this helps this site or its base of information? I don't glean any enjoyment of denying reputation points, but don't see any good in this either; only "filler" on a search with that tag. (If you were looking for the question, you'd still be able to find it using the title so that's a dead-end.)
This edit is merely to differentiate a story from an author. This was about identifying a story, and when I first read the question, it had been answered and had the answer as a tag. You have to check the edit history to find out if that tag was from the OP or an editor after-the-fact. It is not so much detrimental to the site as ambiguous, clogging and unnecessary. When the question is answered it seems like nothing more than to get a couple rep points for an edit while adding nothing to the question or answer, and possibly bogging down the search using tags with info that is of no use. How is knowing user9374 did not know the story, but remembered details, going to be a useful trait of this site when we try to discourage fluff and over-commenting and other things that deviate from a pure and trust-worthy Q&A site? We need to monitor tagging as much as commenting and spamming. /end rant
