Are blogs more polarizing now?

Than they were a year ago? Interesting post at AndrewSullivan.com Yes, there are always those small-minded people who just want to 'preach to the choir' and there are people who are comforted not by knowing they have the best argument, but hearing their views constantly affirmed. And there are netizens who function more as political operatives whose currency is fear of the "other" -and both major parties do this really well. But the good news is you are free to make the blogosphere whatever you want it to be.
