With a podcast like the CultCast, you can drop in and start listening at any time. News-based podcasts are meant to be listened to, and then discarded. Another one will be along soon. But what about more structured podcasts? Podcasts that work episodically, like a TV series? With those, you want to listen from episode one, and listen in order — episodes 2, 3, 4, etc.
But podcast apps don’t let you do this. They’re geared towards disposable, periodically-updated podcasts. They may show you a list of previous episodes, so you can tap to download them manually, but then it’s no longer a podcast.
What you need is a service that takes any podcast feed and rejigs it, serving you a new episode each week as if the series had just started.
