Am I the only one who finds this more than a little surreal? I mean, they have Kos as right of center, for crying out loud. And Lileks as center-left. It's especially bizarre coming from Online Journalism Review, which doesn't have an ax to grind with any of the blogs on the map.
Of course, almost all attempts to map blogs according to politics are doomed to fail if you plot on a single left/right axis, rather than a quadrant approach similar to the one at Politopia. However, some of the measures here are a bit off. The story does not indicate how the politics of each blog were quantified, or the period during which the measurements occurred.
