In looking at the HTTP logs, I know that there are people who scan the download directories for the podcasts. The file name convention we had been using for the first year was:
industry_misinterpretations-00-00-00.mp3
Where the numbers correspond to month-day-year. I've decided to forgo that for the next year - instead, the new file name convention will be:
industry_misinterpretations00.mp3
Where the numbers correspond to the episode number. There could be a -1 or -2 (etc.) for multi-part episodes. That ought to make tracking the shows by episode number easier :)
