I do admire Dave Winer if anyone was ever totally unsuited to creating audio content surely it must be him. That said he has some interesting ideas if a little kooky and I really enjoyed listening to his 7th May Podcast there were some good conversation points.
Dave clearly doesn't give a crap about what I or anyone else thinks and I find that refreshing but he really sounds like 60's hippie surfer dude. When I listen to him I get a mental image of an aged Big Lebowski.
