I agree Taibbi is biased, what makes him a good example for a new model of journalism is that his bias is a) clear and b) not hegemonic. Let a thousand Taibbis bloom each with their own worldview, hangups and bugbears. That seems like a much healthier landscape than the boring, hegemonic left-y (but not Bernie lefty, because his fans are sooo mean online) milieu that we have now.
