Although I haven't mustered up the courage to put together my own podcast, I have managed to get into a couple others.
The Art Institute of Atlanta
Aaron Walter graciously asked me to speak to his class at the Art Institute of Atlanta. I basically ramble on for way too long on design and freelance. The first 13 minutes has me talking about how I got into the industry. The next 17 minutes, I talked about English360 and the process involved in that. Finally, I chat about my own site and the progression it has seen over the years along with some of the reasoning behind the decisions I made. The last 15 minutes or so, Aaron asked me some freelance-specific questions, as well.
Paul Boag (of Boagworld) was nice enough to allow me to come on and chat with a few other fine folk for the .net magazine podcast. This was a lot of fun and I'd definitely do it again.
The only awkward part for me was when asked about Apollo, I feel like I didn't explain it very well. Ryan Carson stepped in very nicely.
.net is a UK magazine and is also known as Practical Web Design in the States. It's one of the best web-oriented magazines I've seen.
