Notes on Defining of Computer-Mediated Communication, by John December
CMC Is Situated in a Human Context
Imagine trying to escape the world itself. Where would you go? Just as you can't stop communicating, there's no place where you could go without being somewhere. Similarly, all acts themselves are situated in a social context.
What excites me are the human imaginations and relationships surrounding CMC. Like an organ in a body, I don't believe a particular act of CMC can be understood without considering the social systems in which it takes place. You can put people in rooms and have them communicate via electronic messaging under a variety of conditions, but I don't think you'll find out anything particularly profound about this kind of communication isolated from a use context.
