Hello?
Is anyone listening?
I sometimes wonder whether bloggers only blog to hear themselves think. Certainly the political bloggers are uninterested in comments.
The last few political blogs I have read required registration in order to post comments - and usually kicked off anyone who didn't respond to every post with a "Well said! You're absolutely right!"
Who needs posts like that? You obviously know you're absolutely right, otherwise you would have written something else. That's what ego is all about.
What you need is to kick the bobbleheads off your site and print the objectionable ones. This will have three benefits.
1) You might learn something.
2) You get free fact checking.
3) Your supporters will sympathize with you, getting all these nasty posts, and neutral readers will pay attention to you - after all, you're so "controversial".
