Ask HN: Why is there a disproportionate amount of interesting text vs. spoken content?

I think it's just a lot easier to 'iterate and improve' on a piece of text - to do the same for a podcast would basically reduce it down to reading from a dry script, leaving it likely even more boring, regardless of how interesting the subject matter is.

Of course, the easiest way to make a programming podcast both interesting and entertaining seems to be just to get Simon Peyton-Jones in it ;).

Producing audio shows is not easy -- it seems everyone can do it, but the really good ones are made by people who formerly worked for radio and TV stations.

You might want to try the TWIT podcasts (http://twit.tv/). I'd call them easy-listening tech shows.
