The federated concept is nice. But I feel like what will happen in the end is that most of the content will end up on few instances. This still gives power to the owners of these instances, and if they delete the instance a lot of people would lose accounts?
What would be your ideas to improve this and have less centralization?
Make it trivial for users to move their accounts between instances, and very hard for instance admins to block. Ideally it would be possible to migrate an account even after an instance shut down, but that is probably impractical to implement.
We also need to consider how to mitigate the threat to communities (I think that’s the term. Lemmy’s equivalent of subreddits). If big communities are tied to specific servers then we have the same issue with server admin power.
