Ah. A completely satisfactory geek experience. Now that I've rassled most of the basic podcasting stuff into shape, I wanted to move on to doing interviews and conference calls and recording them — Ralph pointed out that Skype was the way to go.
Doug Kaye (the maestro of IT Conversations) put together this definitive post on how to record Skype calls. There are other ways, but this is definitely the industrial-strength approach.
I'm going to start doing “conversation” podcasts, but before that I'm going to use this to record an interview for a consulting project I'm working on — tomorrow. I have a little rant n'record that's going up on Sex and Podcasting about how you could use podcasting as an organizing tool for work (the show will go up in a day or two).
