Are you a devoted social network user? Are your students ardent social network users? I’m going to take a wild guess and say that you answered ‘yes’ to at least one, if not both of these questions. Of course, I don’t want to assume that every man and his dog has a Facebook profile (although I have heard of a few cats that have one), it would be hard to deny the widespread use of social networking applications. Seeing as this is the case, why not use them for teaching?
