Hyperpersonal Communication is what happens when you interact with people online.  This is characterized by the following:

“visual anonymity, lack of identifiability, asynchronous interaction, uncertainty reduction, or a combination of these have all been implicated in heightened self-disclosure online” (Joinson, 2004, p. 472).

The interaction and communication online lacks visual and verbal cues, mostly text based with a few images, and you can respond and reply whenever you want to.  Interaction online is different than interaction off line.  You can’t treat it the same.  It’s a different interaction.  It’s not as immediate or even physical, but can be just as emotional.

What’s the point?  Simply that there’s a difference.
