I don't understand the Fediverse entirely. So I don't understand why this is necessary. I thought these were all connected already. I'm from lemmy.world, looks like you're from slrpnk.net, I see others from piefed.zip, lemmy.ml, feddit.uk, communick.news, fedia.io, etc. etc.
Don't we all already have a single identity across all these platforms?
