There were/are some very knowledgeable people who frequented the Apple forums, at least the ARD and Server portions. I haven't been there in a while but when I had a problem that I couldn't find a solution for I was almost guaranteed to find it there. To bad.
The best part is that people were there to ask and answer computer related questions. There was no AppleOutsider (PoliticalOutsider) BS that spewed in to the other sub-forums.
