As I don't have much time to blog today, I'll just do another link post.

There are a number of different opinions in economics about public policy/research (a point which can be lost in undergraduate level classes). To avoid bias, it is often useful to check what persons of various  persuasions say on a given topic, then weigh each of their arguments yourself. To that end, here's a list of some of the blogs/sites which I've found useful in avoiding groupthink (at least wrt debates in economics).

Note: These categories, as with most labels,  are approximations of truth, and tend to gloss over important differences. For instance, libertarians/austrians get mixed up the with center-right. Should be taken with a large grain of salt.
