The Cato Institute has launched a new cross between a monthly magazine and weblog called Cato Unbound. The site will feature a monthy feature essay followed by solicited responses and then reader discussion. Leading things off, editors Brink Lindsey and Will Wilksinson have lined up a thought provoking list of three constitutional amendments public choice theorist James Buchanan would like to see. Akhil Amar, Alex Kozinski, and William Niskanen are slated to reply. That’s a great line up to launch with. If it’s any indication of things to come, this will be one very interesting weblog.
