((Basically saying partisan media will destroy democracy.))

Social observers have fretted about information segregation for years. Cass R. Sunstein, a professor of law at the University of Chicago, argued in his 2001 book "Republic.com" that the Internet's ability to provide personalized news - to permit users to filter out those things they don't care about - posed a threat to democracy itself.
Democracy, he argued, depends in part on people's being exposed to information they would not necessarily have chosen for themselves. So, too, might the concept of gut rationality be endangered in a filtered world, where people see only what they want to see, hear only what they want to hear, read only what they want to read.
Still, perhaps all is not lost.
In his new book, "The Wisdom of Crowds," James Surowiecki argues eloquently that "under the right circumstances, groups are remarkably intelligent, often smarter than the smartest people in them." That's because a diversity of experience, opinion and knowledge can render the whole greater than the sum of its parts. Whether a more partisan news environment undermines or enhances the cognitive diversity of American culture - or diminishes the "gut rationality" of the public - remains to be seen.
"The public's judgment has been pretty good over the past 75 years, when we pretended that we didn't have a partisan media," said Maxine Isaacs, a lecturer at Harvard's Kennedy School of Government. "Everyone knew that we did. It's now just more overt."
