One of my favourite podcasts is Leo Laporte's This Week in Tech (TWiT). Very high production values and good, current topics. Leo and John C. Dvorak (not my favourite) have started a new podcast called Triangulation, in which they have three experts (presumably they will always be two of the three?) discuss a given topic. For their first episode (29 minutes) they are joined by Larry Lessig to "discuss the furor over Google Print". Just downloaded this AM and will listen on the way home, so I can't tell you if there's anything new involved, but I'm sure it'll be solid information.
