What happened to Matt Taibbi? Everything or nothing, depending on your vantage point. Taibbi is, arguably, as ribald and fearless as ever. It’s just that his targets and topics have begun to shift. He does not write as much on Wall Street or corporate skullduggery anymore, preferring to train his sights on the campus left and the talking heads at MSNBC. Taibbi’s defenders say he hasn’t changed. Rather, it’s the world that has grown more illiberal and hysterical.
