% of overall profiles is probably low; there are a lot of bots on these social networks. But real, active users? Once that starts to decline, Facebook is dead; and I’m not sure they can tell bots from humans very well. Facebook has a lot of data; but it turns out every company that advertised with them turned around and used that data to essentially build their own customer targeting databases. Facebook’s data policies were very naive, and it’s coming back to bite them now that user expectations have come around.
