I see when I look at other facebook users pages, there are 3 pictures under the main page picture... These same pictures change here and there... Does the order they appear in represent who the page owner has had contact with last? Is there a direct correlation between the two?
Can you provide more details? Screenshot? Basically FB (everywhere) shows the most active users at top. So for example if you look at FB page of some user and see its friends than the friends showed at top places are usually the most active in relation to that users.
