My reader's opinion. In sci-fi or fantasy story - more fetishes = better. It makes the world more alive, more varied, more fun. Yes, even if fetishes are turn-offs for me. But when it is a real-world or real-world-like story I expect some consistency. If a story is some romantic sweet thing and suddenly someone adds a hardcore non-consent piece... FUCK YOU WRITER. And I like non-con when I am in the mood for reading those.
Personally I avoid outright non-con despite interest in consensual non-con simply because my audience leans female. Myself and many women have been subject to genuine non con, so I do try to maintain a rigid line for the sake of my audience.
I'll be honest, I don't really like the collaborative aspect of this site much. I'd prefer each story/branch be written by the same author and thus have a consistent style and tone. It's also why I can't get into American comics, the thought of some random new artist butting in is just plain unpleasant to me... Keeping each plotline to one author keeps things consistent kink-wise, too. Johnny Romance is probably not going to shift into hardcore bondage from one chapter to the next...
I present to you: the beauty of Private stories. You start out as the sole approved authors, and can add others for other character lines. Great example is my story (serious WIP, probably should advance the version number slightly though). I'm the head author, and so write the shared chapters, but each character gets its own story line, but they will converge on a single location and event, cause there's only one BBEG
