Social media allows social networking to happen very efficiently. This is not what Facebook does. In fact, the most efficient social media network on the Internet is Twitter. This is because Twitter allows one person to inform millions of people of a fact in seconds, and start to see responses and direct replies within seconds. Facebook is popular because it is user centric, and is the first social media network to put the user first and to literally focus all of the attention on the user and what the user wants to say and portray about him or herself. This is what MySpace was trying to do but eventually failed against Facebook.
