I don’t think normies care, and i believe essentially it doesn’t matter.

But I haven’t done any research or spoken to any users, so I’m just going off instincts.

Happy to be proven wrong. I’m not a fediverse expert.

Oi mate! Ya got a loicense fer dat dental advice?

Reddit doesn’t really care; they’re going to do the bare minimum legally so they can feed more ads and get more clicks.

It’s awkward for me because the comment feed feels very segmented. It’s awkward to have a big header for a smaller/niche instance and one comment below it.

It makes that comment seem like an orphan and gives prominence to people who use the biggest instance.

I’d also want the sort I apply (Hot/New/etc) to apply to every comment, not per instance.

I’d propose something like this.

Clicking on the Server dropdown could be a simple checkbox group, which would remember your configuration across that instance. That way, if you wanted to hide specific communities from appearing, you could.
