context collapse (s.v. "context collapse"): A concept used by academics writing about the effects of social media. It refers to the infinite audience possible online as opposed to the limited groups a person normally interacts with face to face. In a limited group, a person is constantly adjusting their tone and presentation of self to fit into the social context. In a situation of context collapse, this becomes impossible. In addition, behaviors and materials intended for a limited audience can suddenly clash with parts of the wider audience they actually receive. (†1883)
