Social Technographics defined

I hadn't heard this phrase used before to describe the various roles users entail when using/interacting with social technologies.

This online slide presentation from Forrester quickly outlines the multiple roles, which are:
Creators
Critics
Collectors
Joiners
Spectators
Inactives

I think many users can operate in multiple roles depending on the social network and tasks at hand.

These role definitions also offer a nice conceptual structure in which to introduce students to the current internet landscape of production, consumption, and socializing.
