I'm the guest on the StackOverflow podcast with Joel Spolsky and Jeff Atwood. w00t!
We talk about everything from early internet history, to IPv6, to how to scale a really really really large web site. Here's the episode page and link to the audio. (Tons of links on the episode page).

Thanks to Joel and Jeff for having me on the show! I listen every week!
