Polarized Politics and Blog Readership

According to a report in the WSJ, two-fifths of Americans who are online have read a political blog, and more than a quarter read them once a month or more. The results of a recent Harris Interactive poll also indicate that individuals who report themselves as Liberals are most likely to post comments on a political blog. To what can we attribute this, I have lots of thoughts. but no answers. But, there is one thing for sure, our polarized politics are clearly visible here.
