Facebook’s new Graph Search tool gives users who allow followers — formerly called subscribers — a way to learn about their audience.
Facebook launched asymmetrical following in September 2011. Users can allow followers to see their public updates in News Feed, similar to Twitter. The feature is commonly used by public figures and people who use Facebook to connect with people in their industry or who share similar interests. However, unlike with Facebook pages, users do not get any analytics about the audience that follows them.
