In the genre tag selection dialog, it says “Select a tag from the dropdown or type to create a new tag.” but when I type in a new tag, it tells me that it’s added as content tag. How would I add a new genre tag?
In case you wonder which one that would be, I found that for non-fiction there are not many genre tags that can apply to them, so I wanted to add “Interviews” for アンダーグラウンド | L33.
If I remember correctly, there was a lot of discussion about what should constitute a genre tag and what shouldn’t, and people tended to have strong feelings about it. In the end I believe it was decided to keep genres “clean and tidy” and allow users to only add content tags. I tried to find a reference to that (I remember it so clearly), but this is the best match I could find:
I’m sure there’s something more official somewhere?
Of course if users aren’t allowed to create genre tags, the UI shouldn’t be misleading about it, I agree. 
I was not sure what the verdict was in the end (I remember that there was a bit of a back-and-forth discussion around it) but if I can create one but not the other, then the UI should be different for them.
There was a bit of discussion in the background with the tag managers (or whatever we are called) as well and at some point genres were logged and the discussion died, I think.
Personally, I’d just mash all the tags into 1 and not distinguish between genre and content (and potentially just add something like non-fiction in the description - since descriptions are searchable), but that’s just me. media type, genre tag, content tag, … lots of classifications going on.
Content Tags were restricted for creation. Not sure if that’s the case anymore but this is something that should be raised to Librarians and Tag Moderators, and maybe should have a community vote/discussion.
If the issue still persists, it should be handled here
