Jay Rosen on the role the Internet plays in the media sphere:
Now we can see why blogging and the Net matter so greatly in political journalism. In the age of mass media, the press was able to define the sphere of legitimate debate with relative ease because the people on the receiving end were atomized—meaning they were connected “up” to Big Media but not across to each other. But today one of the biggest factors changing our world is the falling cost for like-minded people to locate each other, share information, trade impressions and realize their number. Among the first things they may do is establish that the “sphere of legitimate debate” as defined by journalists doesn’t match up with their own definition.
In the past there was nowhere for this kind of sentiment to go. Now it collects, solidifies and expresses itself online. Bloggers tap into it to gain a following and serve demand. Journalists call this the “echo chamber,” which is their way of downgrading it as a reliable source. But what’s really happening is that the authority of the press to assume consensus, define deviance and set the terms for legitimate debate is weaker when people can connect horizontally around and about the news.
