Some kind of unified account creation would help with this, I think. Something where you create an account somewhere “central” (which I get is kind of antithetical to the fediverse mentality, but work with me here), and then can “link” that account to multiple fediverse servers.

Right now, I can create an account on pawb, and I can create an account on yiffit, but even though they might have the same username, they’re completely separate. It’d be ideal to be able to link those both to a single ‘meta’ account, which would then allow me to log into and browse either service, while maintaining a unified post history, etc.

Basically, someone clicking my profile on either service would see my global post history across all fediverse services I’d linked.

This could indirectly assist with the discoverability issue slightly. Rather than being on Mastodon, trying to view Lemmy threads, and seeing only new things where specific tags were used, the user could link their account to Lemmy servers (or other Mastodon servers or whatever), and be able to use one unified identity to browse each of those services independently.

Technically there’s nothing stopping someone from having accounts on multiple services now, but having those accounts be completely independent kind of defeats the purpose.
