Arianna is conquering journalism?

Editor & Publisher reports today that the Huffington Post, which didn’t exist until 2005, had more unique visitors than the Washington Post web site in September.

It doesn’t help that the Post editorial page has drifted to the right for a decade, that the editors allow for gross inaccuracies and distortions by one of its most prominent columnists, or that it has decided to diminish the Washington Post Magazine by striving to make it “lighter and happier.”

I’m not sure what’s more amazing about this: a) that a political web site started up four years ago by a wealthy left-wing celebrity has build a bigger online readership than a legendary American newspaper, or b) how rapidly a legendary American newspaper continues to shrivel away both in substance and reputation.
