Atlantic contributor Jeffrey Goldberg started his very first blog this week, with a charmingly naive post mostly about how he knows nothing about blogging but does sit near uber-blogger Andrew Sullivan. "This is almost certainly a mistake," he begins, and it turns out he's 100% right. When the New York Observer's media blogger Matt Haber (the forgotten Gawker Alum!) devoted a post yesterday to basically announcing the existence of Goldberg's blog and needling Goldberg for his initial boneheaded support of the Iraq War, Goldberg blew up with rage. Haber's post was a mugging, he says. Jeffrey, Jeffrey, Jeffrey. We'll show you what a mugging is.
