I have never been too hesitant to take credit for the audio quality of my podcasts. I do read well, and the "Stories" have been pretty darn good, if I do say so myself. And I do, often.
Yet much of the quality comes from the nice hardware I get to work with. My sister bought me a brand new laptop, and a Samson Zoom H2 Handy Recorder, for a late Christmas present last year. About $1000 US for alla that. And the Zoom makes me sound much better than I used to. And the laptop makes editing a whole lot easier and faster.
So I have to say "Thank you" to my sister for that. I read and speak well enough to do right by the equipment. I gather folks like listening in particular to the "Stories from the Hiber-Nation" shows. But gotta give credit where credit is due.
