I only noticed for real because I have one lovely member of my f-list who tends to post several short comments throughout the day. I enjoy them and they make my day go by faster. I'm not good at noticing what isn't there so it took me a few days to notice I hadn't seen any updates from her. I probably wouldn't have noticed even half as quickly if someone more eagle-eyed than I hadn't noticed I was missing from her f-list.

I admit I've friended too many people for what I can legitimately keep up with as I'd like to but I really enjoy the diversity of ideas that travels through my f-list.
