Nobody reads podcast notes. Ok, maybe you do. I don't. I hardly look at the cover art. Podcasts play on my dock as I work and they fly by, auto deleting as soon as they're listened to. Sometimes I hear a nugget of something while drifting in and out of consciousness as I work and I have to reach up and rewind because I think I should be paying more attention. So, at least you know that I do pay attention to some of what is being said and if everyone pays attention to at least a tiny chunk of your podcast, your goal should be to have enough listeners so that the whole podcast is listened to. Maybe it takes 20 different people listening to your one hour of podcast to make this happen but hey! Twenty people!
