My observation is that your naming convention for your podcasts needs to be re-thought. I suspect most people are like me in that they download a variety of programs and not just from Errington Thompson. In consideration of that, your should name the download files in a way that suggests which show it is. The convention of naming it “Show…” may actually do that, but the connection is fairly obscure; it assumes that no one else would choose this same naming scheme and that your listeners remember your code-name, “show”.
