asacp is one that I can think of thats a 7 under the adult directory...for good reason
All the others that used to be 8's (there was an adult humor blog that you could get listed in pretty easily) have lost 2 PR points in the last 6 months.
AVN kinda surprised me but they recently did a face lift so maybe they havent re-optimized very much
they dropped all of the link exchanges they had and have started over, which probably affected them the most
Urb...Ive seen Yahoo experimenting with Inktomi results instead of Google a couple of times....nice boost too
hopefully a shot of things to come...
