I think it'd be incredibly helpful if you added a "Top 8" (or some #) to our activity page that could only be seen ONLY by yourself. It would be much like the "crushes" in the yearly stats, except we choose who to add to our own Top 8. Then by clicking on each we can see only their activity. this way we can see filter in the activity for the people we actively follow.
it would just be a quicker way of sorting through our Network page and finding them and going to their profile to see recent activity.
