@hrefna AP based fedi (not to mention the fake decentralized stuff like bsky) is not well suited to single user instances.
You can't leverage shared moderation resources, or the aspect of instance as a privacy union that makes it safe to forward reports to other instances or post links to external sites without them being able to track who shared it.
We can build a new fedi with autonomous identity & flexible hosting, but it's a big project. And until then, well-run shared instances are the best path we have.
