Re: New diavloggers we'd like to see
I think Josh Knobe should get Kwame Anthony Appiah to come on Bloggingheads some time. They could talk about experimental ethics, since that's Josh's schtick. Then Appiah could come back and talk about liberalism or multiculturalism or identity politics with a particularly thoughtful conservative another time.
I wasn't happy with Cass Sunstein's fuddy-duddy position on the web, but I'd love to see him come back and talk about originalism or Obama (whom he knows and supports) -- or Roosevelt's "Second Bill of Rights" or just about anything.
Richard Posner would be pretty interesting -- maybe pair him with Sunstein?
