Must We Talk? - New York Times:

Of course, these ideological divides are small compared with the ones in the blogosphere, which is one giant version of the Colorado experiment. You can always find a group online to affirm your brilliant opinions. It’s immensely satisfying, but it can also make Election Day a miserable experience. Tonight, you can’t help noticing how many ignorant people out there disagree with you.

The "Colorado experiment" he describes is where the cities of slightly "left" "Boulder and slightly "right" Colorado Springs each had independent roundtable/town hall meetings on some of today's issues and the result was that Boulder moved more to the left and Colorado Springs moved more to the right - each driven in the direction they were going as a result of their isolation from dissent or their unification against the minority view expressed in the meeting.
