I have been a member of AdultFolio from the start. I find I get more work through this site than the others as they allow people to see exactly what you do and not just cover it with the term Adult.
AF is the best site I have seen for balancing both artistic freedom and privacy. Everyone can be who they want to be, whether more limited in scope (art nude/ glamour) or wide open (porn /fetish), the choice is yours. I think as a community people on AF are also supportive of each other's work, which I appreciate. My hope is that it will continue to grow and become the leading site for models and photographers to find each other and book work.
