I honestly don't think it has anything to do with cam sites versus video content sites, Sean. The model is the same for good porn. People will pay to see it if there are hot ads for it out there. I do agree that people shouldn't be putting up entire scenes, but free hot trailers that might include one or two cumshots sprinkled throughout (just enough "money" to entice them into handing over theirs) are a great venue through which to court new traffic.

There are essentially two kinds of porn fans: Those who will watch anything just to get off, and those who want to see the good stuff. The former will probably cruise the free sites and jerk off to anything. The latter will stick around and pay month after month because they know exactly what they are getting and probably won't be able to find it anywhere else. That's why niche sites have become so popular among folks. There are too many mega-sites that are similar to each other now.
