We have to solve the content curation problem IMO. If we all love lemmy.world or sh.itjust.works and post 1000's of hours of content to either and one of them just "shutters" the server then all that content is GONE. Or, am I missing something about how all this works?
If we want to "join" servers we need some type of content migration tool that allows the user to determine where their content is actually "hosted".
We may see individual servers for heavy content creators as they'll want some way to ensure that all of the federated servers can continue to access their content right?
