Is it the Downfall of porn?

Yea. It's not hard to be a porn star. You can literally become an at home porn star in minutes these days. After reading what you wrote there, I cannot resist recommending something for you to read. It's not bad, but I think you might find it interesting. It's Donny Pauling (EX-pornographer's) blog. I think it's called Donny's Ramblings. It'll blow your dang mind. I really like Donny though. He's kind and very, very honest and although our mini friendship exists online only, I think he's a very approachable, admirable person. I suggest taking a peek at his blog. They're WAY more than just crack addicts! Also, I have a big feeling more than 90% are crack addicts as well. It's a tough, tough world in that industry.

I don't watch anymore but this is a topic my friends brought up after work. I think all the interactive porn sites make that possible

Agreed. Or I appreciate websites like PassionHD.
