What Blog Has Taught You the Most?

Sometimes a blog post can teach us more than an entire book. A consistently good blogger can be an especially effective teacher, because blogging enables him or her to repeat the same short lessons in multiple contexts, at a time when each context is important to the reader.

The blog that has taught me the most has to be Marginal Revolution, by economics professors and authors Tyler Cowen and Alex Tabarrok. Day after day for three years, they have shown how the principles of economics can help us understand our world and choose intelligently between various possible public policies or courses of action. And they are gentlemen.
