Economic columnists, surprisingly or not, can be extremely catty to each other over differing economic ideologies. Case in point is this hilarious (well, kind of .. I think so) and awesome article by Naim bashing the Washington Consensus. You can read more of his work here and though I won't say they are all catty, there are some really good resources on alternative interpretations to orthodox neoclassical/neoliberal literature (I'm especially interested to see what he says about Venezuela's growth strategy). I think he does a weekly column!

While we're on the subject, I HAVE to mention Stiglitz for being ballsy enough to stand up to the IMF (and the World Bank) even when it cost him his job as Chief Economist of the World Bank. And while we're talking about bashing the Washington Consensus, you can read Stiglitz criticising the IMF in this New Republic (which is awesome and has some great works) article here.
