A lot of people are talking about federation and access to admins. But what’s missing is defederation policy.
Lemmy is a federated network of instances. If you’re on InstanceA and you make a community on InstanceA, and I’m on InstanceB, I can connect to your community on InstanceA. UNLESS, there’s a defederation- either InstanceA or InstanceB manually block the other. This is something the admins of the instance do.
Different instances have different policies on when (if ever) they defederate. Beehaw for example defederated a number of instances, but that’s due to the experience Beehaw is trying to create- very inclusive and affirming and whatnot. That’s their choice, but it meant defederating some of the more popular public instances (including lemmy.world).
//edit: Another thing relates to creating communities. Any communities you create will ‘live’ on your instance, and thus be under your instance’s rules. Some instancess are friendly to questionable subjects like piracy and NSFW material, others are not. So even if you don’t today intend to create any communities, it’s good to be on an instancewhose rules align with your own preferences.
Google for polyphasic sleep. By fucking with your own sleep schedule you can reduce the number of hours you sleep while still getting the same restful effect. There’s a few different schedules, some work better than others. The concept does work though, I’ve done it.
