The first thing it is doing, clearly, is that puts all the activities my friends are doing into a bucket and then it shows them to me slowly one at a time. Makes the site sticky. I am riveted to the site because its showing me the slo-mo-play-by-play for all the sheep throwing etc. Great.
In addition, it seems to differentiate between push and pull. Not every activity from some of my friends is shown to me on activity feed. If I go to their profile page, I can see these activities - so they are not hidden from me. However, they dont show up on my activity feed. Why not? One possible explanations is that facebook is somehow calibrating my interactions with my friends and is showing more more of some friends activities than others. This is an interesting and scary possibility. Another (more likely) possibility is that I just miss some of the activities it doles out because I am not logged on. Yet another possibility is that it looks at how many friends each person has and ranks the activities of my friends who have many many other friends lower than the actitives of my friends who have just a few other friends. All of these seem plausible from my experience of the site, but the middle option seems most likely.
