It's pretty typical for bloggers to take weekend breaks, but I have to admit everytime there is a time gap between posts on Where's Raed?, I am going to be concerned. His last post from Baghdad was close to a day and a half ago, just before the "Shock and Awe" campaign started.
UPDATE: He returned to the b-sphere Monday, after his internet connection had been cut off. Check his site out, and check out The Agonist, which is the best up-to-the-minute source of news on the war anywhere in Christendom.
