Media I believe that the media exerts tremendous power on people. I certainly subscribe to McLuhan's view that media allows humans to perceive the world differently. The world in which we live is rich with media, and most of our interactions with the world are today governed by some form of media. In McLuhan's day it was television, radio, newspapers, and telephones. Today, those are one device, and we might have three or four of them in our houses, and at least one on our person at any given time. Even face-to-face communications are governed, interrupted and sometimes even mediated through media. The information that we receive about the world almost always comes via media. If not, it comes from another person who did receive it from the media. McLuhan's point was that our world today is much different than the pre-technology era with respect to media. For most of human history, people more or less only knew what they could see, touch or hear themselves. Many were illiterate, unable to consume what media did exist. As technology has proliferated, there are more media forms, and they provide us with more information. Arguably, almost everything a 21st-century person knows about the world has been mediated through one form of media or another.

If media is ubiquitous, and for most of us it is, then it has to change the ways in which we perceive the world. This was one of Stone's (1996) main premises -- that people do...

This can sometimes remove barriers to free communication, as people do not focus on differences. It can, of course, also erect barriers to communication, as the basic respect we normal afford others can disappear when we fail to associate the bits on our screens with the living, breathing humans behind them.
As to our beliefs, we absorb knowledge via media, and have for a long time. When holy books were our sole media, they managed to have a profound influence on our perceptions of the world. Today, when we consume media, it can be difficult to discern fiction from fact, as both are presented the same way. Both are, sadly, transferred to us via the same screens, and the same printed pages. Our beliefs about the world need not be grounded in any sort of reality at all, as evidenced by the state of our political discourse and how uncritical too many people are when consuming such discourse. We have a lot of media, but not much media literacy, so yes, our beliefs about the world can be very much influenced by the messages that arrive to us via various media forms.

Boyd argues that networked publics are characterized by certain dynamics. Such publics will each of their own codes of behavior, but often there is little official policing, leaving members of the group vulnerable to outsiders. Each public has come together on…
