Your comments make a lot of sense to me. I agree about the 'jackpot' unknown. I do not use chat, yet I have a 'InitialChatFriendsList' that seems plausible to be "who views me" moreso than "who I view". What do you think?
I tried this today for the first time. I think the list is who views my profile, in descending order. I have been on fb for 5 years, and I use chat approx one time/year. So this list is not related to "chat" interactions for me. I have 400+ friends.
My #1 & #2 are my daughters with whom interact often and both ways. Next #3 is a friend whom I rarely view, but she often comments and likes my stuff, so I know she views me. #4 is my brother whom I do view often. #5 is literally an old almost-married-him boyfriend with whom I have occassionally messaged in the past about reunion stuff, but nothing except messaging and I only view his wall 2ce/year. #6 & #7 are nice people who kinda bore me but for some reason I fascinate them, (sounds arrogant but that's the short explanation), so it totally makes sense they view me; I never view them. The next 10 or so include some people I view and interact with, but also an equal number of people I rarely eventhink about.
