Most people are already happily migrating to IM platforms where they can contact people more directly and form relevant ad hoc groups. Facebook was smart enough to recognize that and buy one of them. I'd be interested in seeing action metrics over time for FB. My gut feeling is that people use it more passively these days (I do, it's mostly a fancy contact book for me). Every now and then I catch myself posting stuff for reasons of "look isn't this great...please like it" but for the most part my FB use is fairly passive these days. I also feel like I should just delete my FB account for various reasons every now and then but usually talk myself out of it.
