We've notice our customers are going from mainstream fuck/suck porn to niche based exclusive content.
Have a few that thinking ahead and will take over a larege slice of traffic from each particular niche
Spanking customer is opening his site next week with our exclusive content. long ass tour, but he has galleries for webmasters, every size banner and ad imaginable, free content, pre-made galleries, etc., and is also buying search words from SE's, and more....think it will do well.
