My podcast (with a few others) Money Well Spent, which is a Winter12 Production has been a lot of fun. I definately enjoy doing it. One point of frustration is accurately figuring out statistics as they pertain to listenership, subscribers, downloads, etc.

Our servers show us traffic logs which shows us downloads in the form of hits (or initiated downloads) and the average file size. The challenge is how many downloads were just a preview of the episode and how many were a full download. We know if the file size was 25mb and the average size is 22mb, most of the downloads were complete, but you can never know exactly how many were. You could assume that every preview was 30 seconds and figure out the appropriate bandwidth for that time, but that assumes no one downloaded a second of the episode then stopped.

Feedburner tracks subscribers; howerver, there subscriber count fluctuates in a wierd way and is poorly documented as to what counts as a subscriber. Ultimately, it doesn’t matter, we are having fun doing it and some if not a lot of people are listening to it and hopefully enjoying it.
