I find it fascinating to analyze what make good podcasts work and more and more I come to the conclusion it is an art. As the brothers Shepherd from the Word Nerds already pointed out, this might well be part of the art form of story telling. For history podcasts, my main focus, this certainly is the case. Expanding upon that, the true expression of the art should be found in the fictional podcast, the oral narrative per se. The best example I know in that respect is Namaste Stories.
A wonderful example is given in the latest issue Episode #31 "A girl has to do what she has to do". This is a 13 minute tale which stands independently in the string of tales provided by host, narrator and writer Dave P. It can be enjoyed repeatedly. One is bound to find, as I did, new angles in the story, with each new session. However, the story also works in the first instant.
It would be too much of a spoiler to give anything away from the tale, but let me say this much. The perspective of the story is the teacher who finds a girl in his class that he is attracted to. What triggers the attraction? Something purely sensual? Or perhaps some echo of the past? Could the attraction be mutual and if so, how good is that? And so, with what possible intention could it be that the girl is approaching him now? Listen and find out.
