I added a few links to the sidebar that are worth following. Nate Charlow is a grad student at Ann Arbor who I met when I was visiting schools. Social Science++ is the blog of a friend of mine from undergrad. It focuses on economics, computation, and social science issues. Finally, Nothing of Consequence is the blog of Ole Hjortland at St. Andrew’s on logic and various related areas. In addition to the blog, Hjortland has a great master’s thesis on logical consequence (on which I hope to write a post soon) on his website.
