If your instance shuts down your posts will still be visible on the other servers that your instance was federating with. Which might raise concerns if you want to have them removed, but that's another issue.
On Mastodon it's possible to move from one instance to another, taking your followers and the list of people you follow along with you and having the old account point to the new one. In the threadiverse, the most important feature would probably be to not have to manually re-subscribe to a bunch of communities. I think this moving of accounts from one instance to another will probably become standardized at some point in the future, so that you could for example move an account from Mastodon to Lemmy if you should wish. It's probably pretty far down on the list of priorities though.
In my opinion, the idea of a hierarchy of users as enforced on Reddit through karma is a bit obsolete. I think we're posting and commenting out of interest in the topic or a willingness to help or entertain. If that's the motivation, I don't see how starting over on a different server is such a bad thing; you're not really losing anything. We're not here hoarding upvotes like a dragon hoards gold.
This was thrown around a couple of weeks before the Reddit migration really kicked off, it appears to be excessively difficult to code.
And it also doesn't really fit with the system that Lemmy runs. It's a great idea, but Ive been lead to believe that it is too difficult to create
Although people do feel that account transfer would be a nice feature
This is why I'm not really on board with the people that advocate for others to seek out and join small instances unless they are older, well established, and active.
From my understanding, a current goal is to make any account transferable, in case the instance the account is attached to decides to shut down/defederate?
If implemented, we can hope that won’t be tied to an instance shutdown.
well if we can move to another instance and migrate our saved posts, post and comments history, subscribed community easily this might drive adoption because people are used to centralized platform
