Do you think TGPs serve a useful purpose...

[Bishop]

Not true - All viable adult traffic comes thru TGPs.
Not true - TGP traffic does not covert.
Close to the truth - TGPs are the adult search engines of the future.
Yes and then No - TGPs give away too much free porn and kills paysites.
Not true - There is no money to be made with TGPs
Does not apply - All I run are TGP sites and I make bank.

TGP traffic does convert but its not the greatest conversion.
Yes they give away to much content but take a look at who is buying the ad space on the sites... those are paysites. Paysites can make money on TGPs.

Do I wish TGP had never come into existance? Yep. Do I think they will ever go away? Nope. What would I have prefered to see in their place? Picpost. One pic at a time with a banner on the top and bottom and the pic is a link to the join form. haha.. Seriously I wish free content had never been made so accessible to the surfers but in many ways I think it has made them connoisseurs of the product. They have seen so much of it they have very specific taste and will pay to see exactly what they want.
