I think one of the problems with adult webmasters is their unwillingness to look at and even pay for other porn sites. Maybe some are thinking "I want to be all original, and not copy anyone else" but think about it people. There are tens of thousands of paysites out there, how can you not look at what they do? That's like not asking what's in someone's spaghetti sauce when you liek it better!

I recommend using a directory service like
mine or
this or
this or
this or
this. and pick something in your niche to check out. Even if you just look at their free areas, I think it's necessary market research. Rather than someone tell you what to do, why not do a bunch of research, put the ideas you like on a list, then prioritize and cull the list?
