It seems like information and updates about the same friends keep appearing in my Facebook news feed and there are others who I hear nothing about, even though they've been busy updating away. Why is this?
Well that news feed shows the most recent updates. So if the "Others" updated their stuff like 15-20 minutes ago.... and the same friends updated like 10 minutes ago.... then you'll see the SAME friends because they updated most recently...
Thats the only logical answer i can think of.
OR... they have their privacy set to where their activities do not show up on friends news feed.
