They say that the brain is the largest sex organ, and the thing is with porn is that it is all visual.
My idea is that the most popular/highest rated stories are recorded for people to download. For example, the author of a story could be invited to record their story and upload it to the site (after been checked out for quality etc).
I beleve that this will open the site upto some of the people who maybe have trouble reading....or are just plain lazy.
Anyway, its an idea...
