On Iran, Andrew Sullivan > Î£ MSM.
Megan McArdle offers some reasons why. I would add that MSM is unwilling to rely much on information aggregators such as Twitter and they are reluctant to report things in the uncertain, hanging narrative kind of way that blogs (sometimes) excel at. MSM needs the definitive-sounding soundbites for people who are tuned in for only a few minutes and don't come back or don't come back with any memory of what was said before.
We're seeing a revolution in coverage of current events right before our very eyes.
