Although I have been in Adult since 96, I've always done my own thing, and have very little business dealings with others in Adult. That being said I would say these people I have enjoyed reading, or speaking with and consider them all to be class acts, in one way or another.
Cyberage Dave. He gave me my start in this business indirectly. Always enjoy his videos, and posts too.
Baddog. Very smart, and I was very impressed with a lot of his ideas
Son of Sam. Very hardworking, and persistent, will go far in this business)
2houseplague. Love his posts.
All of the regulars in the GFY IRC channel. You know who you are
Last but certainly not least... The mighty Shoehorn. Shoehorn is a rare breed. Extremely funny, and all around one of the nicest people I've met in any business (not just adult)
There are more I'm missing but that's the quick, and short list.
