Here are a couple of interesting podcasts:
Eriq Neale knows how to run a show. Each is less than 15 minutes long, very professional sound, just plain excellent.
What it's like to write a technical book (specifically SBS 2003 Unleashed)
SBS CSS Team will Podcast on ISA 2004 on Friday. The podcast will be here once recorded. Unlike Eriq's, these podcasts are rough through and through and will soak you for an hour of your time. Still there's bound to be good content from the guru's at CSS.
