discovering podcasting recently. (ipodder, et al).
the whole "reading your blog into a mic" thing is pretty lame, but there are some real uses. for example, itconversations is neat, allows you to listen to saved interviews, keynotes, etc based on techie stuff.
basically its all about "time shifting" again. there are radio shows popping up that you don't have to tune into (you just download and listen to it when you want).
the whole thing is tivo for your ears.
rode into work today with headphones, listened to a few of these podcasts. listened to bruce schiener's interview on itconversations (never knew he had a funny voice). and "the daily source code" with an old MTV VJ Adam Currey.
