> Data is all there. Tagging is categorized to the T on porntube sites by the actor/actress, genre, ethnicity and different acts depicted. I looked into doing this. The problem is that all of the popular tube sites have bad data especially in the tag section. People put up videos with the most searched on tags, even if the content doesn't match. Actress/Actor data is a joke on many sites---being a wild guess at best especially for asian actresses. Still you could take what they have and make it easier to search through. There's some movement on that front in the niches--like hentai, but none on the main stream sites. One thing to worry about in recommendation engines (which is why they're so conservative on the big sites) is that users are enthusiastic about their particular niche but nothing else, and unlike in say Netflix--there's a real possibility of showing miscategorized guro to someone doing a vanilla search.
