Through @doktorzjivago I just realized and have tried myself to post an mp3 file to my Mastodon feed, and then go see it appear as a podcast in my Pocketcast podcast app by placing my Mastodon name as an RSS there. Quite cool! Suddenly publishing a podcast is the same as having a Mastodon account. So now for example a podcast could run its own server and have its audience on it for example. Quite cool.
