I anticipate that Facebook will roll this out slowly and carefully so as not to upset users, and to educate brands about how to get their reach back on Facebook – albeit by paying for it.
I can see why Facebook has been pretty tight-lipped on the matter thus far and not made any official public announcements about it. I imagine that a percentage of Facebook's 1.4 billion users worldwide may not be so pleased to hear that they have changed the way they're delivering content so that marketers can now buy their user information in the form of "targeting options" that include behaviour and location from home. Yes this means that Facebook knows where we are and what we are doing at all times." http://www.hospitalitynet.org/news/4075682.html
