International Crisis Group publishes two new articles about Iraq: The New Sunni Landscape, which explores the al-Qaeda's fall from grace in the Sunni community and the emergence of Sahwa, and the Need for a New Political Strategy. I've only read the first one so far and it's as informative and detailed as the previous Crisis Group reports, describing how did al-Qaeda fail and the motives of the Sahwa Tribal militas and their interaction with the US, the government and rival Sunni parties.

al-Rafedain.net, a Shi'i website with a strong anti-Sadrist bent has been uploading vidoes defaming Muqtada and the Mahdi Army for a long time, their latest is "Shathaat Muqtad'iyya" (Muqtaadi Fumbles), which collects the funny, crude and embarassing things Muqtada has said and done in a three-part YouTube series. Particularly interesting is Muqtada meeting his henchmen in the 2nd video, the similarity to you-know-who is uncanny, minus the crying Ya Booooya guy.
