If you are (re-)discovering the joy of community-built technology that's not controlled by a billionaire, allow me to plug an even older tech:
An RSS/Atom feed reader is a great companion to a more conversational social media "site" like Mastodon.
Google killed its Reader product years ago, but there are still many great ones. I personally use https://newsblur.com/, which also has a mobile app, synchronizes across devices, and is open source. (If you have a favorite, please reply with it!)
(On that note -- podcasts are kind of like Mastodon, spread across servers, except when we let corporations like Spotify put them behind paywalls and subscriptions. :-)

Then there is Funkwhale, the federated podcasting app that you can use the protocol
