I tend not to like link-only journal entries, but would feel guilty to spend the time it would take to comment fully on each of these.
Therefore, here are a few links of interest and ultra-brief notes on why they're here:
http://www.econtalk.org/ : EconTalk. Russ Roberts of George Mason University hosts some very interesting economists and other economic thinkers. He's pro-market at least generally (I haven't heard enough to find any exceptions to that yet). I really like this: "The cuneiform inscription in the logo is the earliest-known written appearance of the word "freedom" (amagi), or "liberty." It is taken from a clay document written about 2300 B.C. in the Sumerian city-state of Lagash."
http://uc.princeton.edu/main/ : "University Channel" -- Princton's set up a very nice page collecting lectures (a mix of audio and video presentations) on several topics;l they're primarily (all?) from lectures given at the several schools which are affiliated with the site. The quality varies, both in production value and content; the Steven Levy lecture (with some further thoughts since Freakonomics) is especially good.
