I'm down with another Other Genre. As for the possibility of confusion, I would think it'd end up like the Genre tabs you see in Manga/Online Comic websites -- like so:
It took some editing for me to do, but this is what Tapas could possibly go for. I think it'd be pretty easy enough to navigate if it's something like this.
Of course, this also begs the question of whether or not the website is at that point where they can change to this layout. It took me 1 - 2 minutes to edit this, but I can only imagine what it's like to actually program all of this and make sure it works, as well as having the money to hire someone who can XD
