The collective blogosphere is self correcting
The individual blogs are not
e.g. Malkin
Her "correction" centred on whether the photo was authentic or not.
No retraction or correction of the original no-one-talked-to-kerry-in-iraq story.
Still waiting on Powerline's correction too....
This is a trivial example of something more insidious. You and I and others are anomalies - we look to blogs for both sides.
Most dont. If they read a wrong story on Powerline and Powerline didnt retract it, that story remains uncorrected in most peoples heads.
