Facebook can reconnect people who’ve fallen out of touch. The social networking site is also a way to reconnect with what irritates you. Facebook floods you with other people’s thoughts and experiences. Sometimes, it’s too much. So you cut and run by “unfriending” -- a new word that means to eliminate someone from your social network. Christopher Sibona has researched the top reasons people unfriend each other. He’s a doctoral student at the University of Colorado Denver.
