That's a very thoughtful feature. I admin a Discord server of 2,600 and while I like the idea of a federated server the cost of getting most people to jump ship to the new software gives me pause. This seems to directly address a large part of my hesitation.
So much great info about software projects, game communities and much more that would have been on forums just a decade or so ago is now locked in discord/x/facebook/etc forever and will be lost to time. It's a form a cancer on the open internet but, what isn't now adays.
In discord it's more like a slack workspace, right?
The people "hosting" a discord "server" are not actually running hardware anywhere that runs the server?
But yes, a Discord server is equivalent to a Slack workspace. It's just inherited terminology.
