Why What You Do in the Real World Matters on Facebook

A pair of studies by researchers at the University of Colorado-Denver explored the ways in which people break connections with one another on Facebook. They found that high-school friends, acquaintances, and co-workers are particularly vulnerable to being "unfriended," and not always for the content posted. "We found that people often unfriend co-workers for their actions in the real world rather than anything they post on Facebook," one researcher said.
