User scaling seems easy enough. Its "community" (on Lemmy), or "magazine" (on kbin) scaling that seems hard. But since each server has a local-copy of the community that its serving out, maybe the hardest part has already been solved by the Federation model. Each federated-instance is effectively a proxy / front-end for the users on that instance. --------- I guess Mastodon is way larger than Lemmy though and they haven't had issues yet.
