I've just added the PODZINGER Search Box to the Instant Movie Blog so that you can do text-based search of the podcasts on this site as well as the podcasts around the web. It's pretty slick technology, and a little bit addictive. Once you start searching podcasts by word or subject, you find your self searching and listening and then searching some more. I wrote an article about Podzinger for PC Magazine a few months back -- take a look at it if you want to know more.
