@Bill - I agree that a lot more sponsors need to use shooting scripts that include the needed dialogue, the required looks and attitudes, the costume dos and don'ts, the necessary reactions, and many other items that key off of the deeper hooks of specific niches. Too much porn is being produced that has almost no chance of influencing a visitor to become a paying member.
The sad truth is many programs have no idea at all what the deep hooks are in most or even all of the niches their sites cover. They keep spending money producing products without ever understanding the needs that drive the consumers of those products. From what I see around the Net in 2011, most of the porn being created is absolutely not worth paying for. Which means that most of it is therefore not worth wasting any time promoting.
And of course you're also correct that increased production costs come with this.
Which unfortunately means that most sponsors who'll spend more on production will offset their increased costs by using cookies with short lifetimes, adding email collectors to their affiliate tours, using 2-step join forms to capture the surfers' emails before they see the real join page, sending mailings with discount offers to the visitors you recently sent to their tours, and lots of other little tricks which ensure that affiliates don't wind up making much more money even on porn which converts better.
Hope that positive feedback brightens everyone's day.
