Unfortunately, the data that developers are able to work with is severely limited. They will simply be able to make a call for a user to Facebook and get back the friends’ streams that this particular user has the permission to see. The data can’t be cached for later analysis, the company isn’t sure yet how far back in the archives access will be permitted (though they say the goal is to expose all the way back), and the Terms of Service will prohibit eyes outside of a user’s Facebook friends from seeing the massive amounts of friend-limited data.
