I originally chose to make my account on lemmy.world since all the content seemed to come from there. But I’ve since learned that I can fill my feed with stuff from any instance so it feels like it doesn’t actually matter if I’m on lemmy.world or not. At the same time, Lemmy.world seems to be frequently under attack so I’m wondering if I should change instance but have no idea what I should even be looking for when choosing.
All refers to everything that your instance knows about. Your instance only retrieves data for which users are actually subscribed.
All can be weird on small instances if the user subscriptions don’t have a nice distribution.
