Hey Lemmy - I'm trying to migrate my life as much as possible into open source tech and platforms. Fediverse networks like Mastodon and Pixelfed have provided good enough alternatives to their counterparts in Twitter and Instagram.

Is there such an equivalent for bloggers? I'm hoping to find a platform which is open source and supports self hosting but one that also provides a first-party instance that folks like me can make an account on and start publishing.

Effectively I'm looking for something that would provide a user experience similar to Medium or Substack but which wouldn't lock me or the community into it. Something based on ActivityPub would be ideal.
