What part of the social in social media don’t these 10 celebrities understand? They are followed by millions yet follow no one or at most only one Twitter compatriot in return. They are anomalies, too, as this is not typical celebrity behavior; in fact, of the Top 500 accounts in terms of followers, only these 10 follow so few.

By way of contrast: Justin Bieber, whose 39.2 million followers top the charts, manages to follow some 123,000 Beliebers. Bill Gates is followed by 11.3 million and in return follows 154, which while not a large number is 154 more than zero. Even Pope Francisco, who’s been on Twitter only since March and has gathered 2.4 million to his flock, has followed eight of them back. It’s only social.
