I'm in agreement with Graeme on this, I write what I write because I enjoy it, plus it allows my sometimes vivid imagination a huge amount of freedom. I can't say for certain if people like what I've done because the story has only been up a couple of days, but from the feedback I have had it seems to have gone down ok.
I really don't think option 1 would work with that many writers, because whilst it may be popular, you're not truly writing something that you enjoy or feel comfortable with. That I feel would be pretty transparent on the page.
I do agree with leshwar though in that you would be better finding a venue that is more compatible with your work. That said, this site more than others I have been on, is far more diverse as regards the genres available.
Just my observations.
