In the middle of a slow holiday news cycle it took the liberals at Think Progress until the publication of Johnny-come-lately stories in the NY Times and CNN to acknowledge the Kingston sludge disaster. Not exactly cutting edge or tuned into the Tennessee social network, are they? And what if big media had not responded after 48 hours? Would it have remained invisible at the Center for American Progress?
UPDATE: In fairness to Think Progress, I should say that Brad Johnson at the Wonk Room did say something about Kingston and post a video in a piece about how the coal industry is attempting to launch a "Blogger brigade" to counter netroots anti-clean-coal activists last Tuesday. Someone there was on top of this. Bygones.
