Lots of Fetish Content Sites, Less Amounts of Popular Niches.
Looking at the list of sites and DVDs content like tranny, mature, BDSM, femdom, and anal are among the largest sections. For instance there are twice as many tranny videos as BJ scenes. I believe this stems from the AVS setup where the individual sites are put out in those fetishes that are best able to attract potential members. The balance here isn't what we're used to seeing from a movie download type site and the collection is more heavily weighted more towards those kinky/fetish categories.
