With all due respect to our own eminent economists, the most potent Econ. blog ever has opened for business. Nobel Prize winner Gary Becker and federal judge/innovator of the the highly influential law and economics movement Richard Posner have begun blogging. I normally hate all the self-referential "blogging is so important" language from many practitioners of the art, but this is a big, big deal and lends a lot of credibility to blogging as a means of communication. Posner is one prolific son of a gun. Heaven only knows how many millions of words he'll fling into cyberspace in the days to come.
