Nice article on echo chambers by Dave Weinberger over at Salon. A few key quotes:
Conversations iterate differences within agreement… The fact that conversations start from a base agreement is not a weakness of conversations. In fact, it’s a requirement.

No, if you want to see a real echo chamber, open up your daily newspaper or turn on your TV. There you’ll find a narrow, self-reinforcing set of views. The fact that these media explicitly present themselves as a forum for objective truth, open to all ideas, makes them far more pernicious than some site designed to let people examine the 8,000 ways Hillary is a bitch or to let fans rage about how much better Spike was on “Buffy” than he’ll ever be on “Angel.”

We are at a dangerous time in the Internet’s history. There are forces that want to turn it into a place where ideas, images and thoughts can be as carefully screened as callers to a radio talk show. The “echo chamber” meme is not only ill-formed, but it also plays into the hands of those who are ready to misconstrue the Net in order to control it. We’d all be better off if we stopped repeating it and let its sound fade.
