All these “why are people using Bluesky and not Mastodon” topics are starting to give me a headache. You’ve been told and on some level, I have to assume you understand the reasons, but are simply unwilling to address them. When people say, “it’s difficult to use” instead of understanding why they think that way, you just dismissively wave your hands and say, “no it’s not”.

If you want people to use Mastodon, you need to SHOW people the power of federation while HIDING all the rough bits. People want to go to where the friends, writers, artists, scientists, etc. they want to follow are and sign up for an account there. Simple as. In this way, they very much want at least the appearance of centralization. I don’t want to have to get balls deep in an instance’s politics to understand their moderation, who they’re federated with, if they have the funds to operate into the foreseeable future, and how to migrate my data if any of those things goes sideways.

Even if that’s not your cup of tea, it has the option to save your notebook to a single sqlite file, so I take that as good enough proof it’ll work for your similar purposes as well.
