Over at Ajaxian, I just posted a ~30 minute podcast exploring this issue, featuring interviews with Brendan Eich (CTO, Mozilla), Kevin Lynch (Chief Software Architect, Adobe), Alex Russell (Dojo Lead), and many others. I had a lot of fun recording the interviews and editing this together, but I probably spent a little too much time doing it. ;-)
I'm interested in knowing if folks enjoy this kind of "feature" podcasts that involve more of a narrative than traditional monologue or interview podcasts. They take a lot of time to produce, but I kind of like having the information dense and relevant to a particular subject...
