When looking through the tags on the Main Site I found the tag fiction. Two of its questions are closed. Two questions use the tags science and fiction, which looks like the author wanted to use the tag science-fiction and didn't know that tags are written with a hyphen when you would use a space in normal writing. There is a total of 4 questions with this tag.
I don't see how it is useful for the site, seeing as we already have the often used tag science-fiction with currently 580 questions. There is no usage guidance or tag wiki that would explain why the author of the first question with this tag, who currently has a bit under 700 reputation, added this tag to the already existing tags. One could argue that "fiction" is a more general term, whereas "science-fiction" specifically states that the question is about fictional elements regarding science, but as WorlBuilding is in itself about creating a fictional world I don't see how using this tag would make questions easier to find. It looks like the tag could be used on basically every question ever asked on the site.
I think we should burninate this tag. What does the rest of the community think?
