Active behaviour tracking on Facebook

Lately, being a more active user of Facebook myself, i have started to notice some interesting patterns. It seems that the more you check a profile, more often that profile will make it into your live/news feed. The more you comment a certain friend or even if you just send private messages to them, the more those friends will top your live/news feed. There are some profiles that seems to feel into obscurity even if they have activity. If you haven’t checked their profile, FB doesn’t bother you with them. I am guessing if you use the feature “in a relationship”, “engaged” or “married”, for sure the -other person will see all your activity on their live/news feed (this is pretty self-explanatory, no?). I cannot verify, but i think the same logic can be applied to photos. You tag people in a photo, FB will know they are part of a friend-circle and increase their feed ranking among them. Talking about big brother… hey’ i think we all got one now! I will think if we can create a similar technology for our content platforms.
