@NatureMC Hosting a podcast with Castopod is exctly the same as hosting a blog with Wordpress.
Castopod is a server application that manages everything you need for your podcasts, plus ActivityPub, plus analytics, plus it is multi-tenant, multi-user, plus many other things. See https://docs.castopod.org for more info.
We also provide hosting services on https://castopod.com if you don't want to manage the hosting yourself. (Exactly as WordPress does.)
