One of the reasons Iโm excited about #Fediprofile (aka https://hub.vocalcat.com) is identity portability.
Right now, people follow accounts. If I move servers, change handles, or create a separate profile for a different context, I risk losing that connection.
With Fediprofile, you follow my profile hub instead of a single account. (My fediprofile boosts all my accounts notes/create activities).
That means:
1. If I move my Mastodon/Pixelfed/etc. account to another server ... I just update my Fediprofile.
2.. If I add Pixelfed, Loops, or another ActivityPub account ... I link it.
I can even create separate profiles (professional me, playful me, project-specific me) ... I can structure that intentionally.
People keep following me, not a specific server address.
And if you combine this with self-hosting on your own domain, you get something even more powerful: one stable ActivityPub actor representing the parts of you that you choose to combine.
