Am I the only one who is hooked on ABC (Australian Broadcasting Corporation) Podcasts? They have a regular radio show on philosophy, and the only more fun thing to listen to than a discussion of philosophy, is a discussion of philosophy in Australian accents. ;)
Of interest to many involved on-line, may be the latest episode of The Philosopher's Zone, as it examines, in particular, Wikipedia. It addresses the main issues, and in a fun way. Give it an ear, if you are so inclined.
