My hunch is yes, there are successful patterns in Facebook that will propagate to many other software categories, both because they are beneficial and users have een trained to expect them... but then no, those patterns won't dominate completely, because certain countervailing needs will change/moderate/negate them.

For example, the 'news feed' is super compelling and attention-grabbing, but at least partially in attention-abusive ways. By intermixing updates of wildly different importance, provenance, and topic, a heightened sense of novelty is created. By the use of reverse-chronological order, a false urgency is created -- "I must read/reply before it scrolls out of view!" -- even when the topics aren't really urgent. So this pattern is a sugar/steroid/stimulant for engagements... against which the mentally-healthy will eventually have to disengage and replace with something more respectful of their attention, with truer cues about novelty and importance.

So I expect the 'feed' pattern to be copied everywhere it might offer a quick bit of 'sizzle' to interactions... but also for new ameliorative antipatterns to be developed, and modify or displace the 'feed', as well. Especially in productive contexts where entertainment/diversion/distraction is not the highest value, it will be tried but then modified or discarded.
