I put together this audio presentation [1] using Audacity [2] software for the Rhetoric Society of America conference. The panel presentation was called "Rhetoric and the Amateur," and each participant tried out a technology that they knew nothing about.
The "Why?" Question is the question I always get when I talk about distance running. If you listen to the presentation (which is, predictably, quite amateurish), you'll get some possible answers to this question.
