The main goal of these sites is link aggregation. It wouldn't be overly difficult for a federated server with its own /c/Technology community to see other posts from other communities linking to the same thing and combining the discussions into a single view.
The tricky part there is moderation, but even that's manageable by allowing moderators to remove content from a federated view within their own instance, it'll just be difficult when a small instance is dwarfed by a larger one.
Completely agree. Great start but room for improvement.
I'm hoping that some of the Reddit 3rd party app developers seize the momentum and either port their apps to Lenny or write a purpose built app. The big ones like Apollo and RIF would draw a tonne of users just by supporting Lemmy.
That's not moving your identity though, that's creating a new identity that subscribes to the same communities. There's an important distinction there, there's no way to clearly identify yourself as you having moved, which conversely also means there's no way to be assured that some other account is not an impersonator.
Don't get me wrong, it's good to know that if a server were to disappear that I could just create an account on another one but it's still a distinction that causes some issues today that will need to be ironed out in future.
That's true if of any power plant though. It'll still be cheaper and safer (if it ever works).
