Marginal Revolution

Weblogs are a glorious source of knowledge for those of us willing to learn something new every day. I particularly like blogs written by economists; they all grasp the ideal blog post's concept: short, informed, and provocative. Marginal Revolution--by economists Tyler Cowen and Alex Tabarrok--is one of the oldest, most popular, and best written blogs. Moreover, it is a clear example of why this is such a great time in history to be a self-learner. Go read Marginal Revolution every other day and you'll be smarter.
