Look at a pie chart of "internet users of x type platform" from pre fediverse. If original internet dies and fedi does take off, it will be the same chart but they will be instances instead of www sites. There are still plenty of those prefacebook, premyspace forums on the www, it's just only a few people use them.

If it’s no big deal why the immediate talk of defederating? And if they get annoying, every one of the instances I happen to follow something on has to defederate to keep the community at the same engagement level. I can personally block instances which is great, but that’s not helpful if the community starts posting there. It’s already sometimes difficult to keep topics together across who knows how many instances, with random defederation it makes it more difficult to experience lemmy with users on different instances.

It’s just my opinion, but the reddit backend wasn’t the important part that we lost, it’s the content and community. If my instance goes to shit I can move somewhere else, but I’m disconnected from my posts, follows, etc. that’s what I care about. Not the tech. I try not to, but I can’t help but be pessimistic on the idea when I feel like the point is being missed entirely.
