According to the New York Times, FaceBook is preparing a mobile app that will allow its users to interact anonymously. News sources even say that the app should be released in the "coming weeks."
The application is reportedly allowing users to sign up with multiple IDs to discuss issues they would not like to discuss using their real name. The goal of the larger social network is probably people who do not want to talk about a sensitive subject without sharing with their friends or their family.
Let's hope that Facebook has predicted pedophiles and a lot of malicious users.
