I wonder if it is possible to move my own account to another Lemmy and take all content with me?
This is generally a massive problem with the fediverse in general — even Mastodon, although you can transfer your identity (i.e. if you link your old account, your ‘followers’ will follow you, and people searching for your old address will find you at your new one …) there’s still no way to transfer your content.
I’ve always got the vibe that the fediverse is heavily skewed towards privacy/temporary/“no permanent presence” folks, so it’s very low on the priority list to ‘fix’ that … but for a hoarder, digital archivist, quantified-self need like myself, it’s horrendous and scary.
Absolutely… also scary that when an instance chooses to no longer exist your whole profile goes with it.
I would like the ability to link/sync accounts for an Omni presence or something like that
It is not. Mastodon is able to do something like this, but no such feature exists in lemmy, at least not yet.
There is an open issue already:
