 Those who treat the internet as an artifact may suggest that we look at the impact of mediation (or virtualization) on communication and relations of power; for example, the fact that certain social prejudices are circumvented because the individual responding to my online application for a particular service is not confronted with my physical appearance. They may also suggest, as Turkle (1995, 1996) has done, that we look at the way virtualization makes the presentation of self and identity more plastic and encourage us to think through the consequences of this for ongoing social interaction. The social constructivists may suggest that we need to look at the assumptions as values embedded in the artifacts as such (as was suggested above). They may, for example, suggest that we consider the implicit assumptions about the nature of communication when considering e-mail applications— for instance, the fact that most e-mail applications assume and emulate the structure of a physical letter. They would argue that we need to trace through how people interpret this ‘letter’ structure to communicate and share objects (such as files and pictures) with others, as well as the sorts of communication such a structure excludes.
