Aside from joining the app because you love podcasts, it may interest you because it has some cool tech behind it. ie) Echo is not a podcast player, but we connect to your podcast player. We give every user their own unique podcast feed, generated with a list of every episode that they want to listen to. This feed can be added to your podcast player just like any other podcast feed. When a user finds an episode on Echo, they just have to tap a button and it will be ready in their podcast player from them to listen to it. Try it out, it's pretty slick in my opinion.
Similar solutions have been built, for instance, Patreon generates custom feeds for podcasts which include episodes available only to paid users. However, this is the first time users have the ability to generate a custom podcast feed, for themselves.
