@deadsuperhero@social.wedistribute.org @atomicpoet@atomicpoet.org we use the same synchronization mechanism that PieFed and Lemmy use, FEP 1b12.

@fuina@mastodon.social ActivityPub protocol does not specify anything with regards to account and data portability.
Mastodon supports migration of the follower collection.
The data portability document you linked is a work in progress by some very smart people at the Social Web Incubator Community Group.
@jonny@neuromatch.social sure! NodeBB has it working now if you want to poke around on BrowserPub, just paste a topic URL into it.
v4.0.0 can pull entire topics in already (assuming the remote end supports it.)
When v4.1 drops you'll be able to do this via the topic URL itself.
@mariusor@metalhead.club @silverpill@mitra.social nomadic identity as I understand it allows you to keep your ID if you switch instances, which is similar but not the same as being able to log into and use Site A using an account from Site B.
