The All-Feed is very important to increase the content-quality of the threadiverse and therefore, ensure its existense. However, for smaller instances, there is only limited reason to put the All-Feed prominent in their UI, because their posts will never be present there. However, if they push people toward their the Local-Feed (which they currently do), people will only stay on their instance and overall discussion quality declines.
So, to truly overcome instance protectionism, we need a new feed, in which an instance can find a good balance between showing content from other instances and its own.
No we don’t.
One of the fundamental strengths of a federated approach is that I can, with no muss or fuss, see only my local instance.
I understand where you’re coming from, but you’re presuming that most instances are simply clones of each other, and that’s not true. (or at least that’s not how it’s designed to be).
For example, my home instance is mstdn.ca. Ostensibly, with a single button, I can focus my entire Lemmy experience on things important to me as a Canadian without wasting through everyone else’s bullshit. Canadian news. Canadian politics. Canadian hobbies, etc…
You’re idea presumes that all instances are trying to carry the exact same content, which is false.
Why does it presume that?
