@wjmaggos @mackuba Wait, wait. If you install a plugin called "pod love", or "podcast love" I don't remember, which creates an "episode" content type. You go to ActivityPub, plugin I mean, and flag "episode" together with "posts" as content which can federate. It should work!
Distinguishing between podcasts is missing, though.
Let's assume you have a site where you talk about sports. You review ANY kind of sports.
The only way to perform a single topic to follow, is creating an author for each podcast "volley @ super sport . ext" or "tennis" or "soccer" etc.
Then you can set your display name to "William" but you'll miss the opportunity to distinguish author bio and podcast description.
Otherwise, with a single author, you run the risk of having follower interested in volley, who receive soccer as well. It's not functional.
Podcast on ActivityPub? There's CastoPod - https://castopod.org
