The very cool "TidBITS#766/14-Feb-05" has an article on podcasting.  This Mac newsletter has been one of may favorites since I started reading in 1991.  I continue to read it every week even though I don’t have a Mac anymore so I can keep up with what is going on in that community.

David Weinberger has an article entitled "The virtue & vice of audio" in Knowledge Management World published for Feb05 that discusses podcasting (he likes the idea) but the rest of the article is his explanation on why he isn’t listening.
