I wonder if Facebook could actually become too big. If everything i write into Facebook will be read by friends, bosses, grandma, and father-in-law, i will probably write nothing or only simple jokes. So there might be a point, where everybody has a Facebook account, but nobody uses it anymore. This might be counter by introducing more controls, but that complicates the interface.
