Apparently not everyone has a face on Facebook. A new analysis of its users has found that only 889 million of them are real. the other 100 million? Probably brands, pets, parodies, and kitchen appliances. Yet Facebook is still including those accounts in its active Monthly User figures. Facebook claimed recently that its active users had hit more than a billion. But the study says that that won’t happen with real, live human beings until some time next year.
