I stopped reading him regularly last winter and stopped reading him altogether about 2 months ago because he had, in my mind, become completely a creature of his privileged background and Washington bubble. Now at least he admits that he is a neoliberal who believes that the expansion of the welfare state is complete.
Obviously I disagree with Matt but it is not generally my habit to stop reading people merely because I have a philosophical disagreement. I read other neoliberals, I read a lot of them actually. But Yglesias has taken to wearing his substantive ignorance of subjects as a badge. As he has explained ad-nauseam, he is a philosopher and is highly trained in logic. Thus substantive knowledge of the world isn't needed, he'll just spot the logical holes in the arguments and ideas of others.
Obviously, I prefer to read people who are both logical and substantively knowledgeable.
