How do you choose an instance and does that have a significant effect on your Lemmy experience?
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.
I think a good strategy is to start on Lemmy.World until you discover a solid list of communities you want to follow. Then switch to a smaller instance that aligns with your interests and bring all your subscriptions with you.
If you start on a small instance you’ll have to do a lot more work to discover communities, since they mostly won’t appear in your All feed. Plus, you’re doing that small instance a favor by bringing interesting communities to their All feed.
Sounds like good advice, stick with what I'm on for now (lemmy.world) and see what smaller instances appeal to me as I explore. I'll probably end up doing this.
I'm also realizing from your post that the All feed is different from instance to instance? I thought it's basically everything from all federated Lemmy instances.
It is, but the content that is federated varies from instance to instance. Instances only federate communities that a user on that instance is subscribed to, so the all feed is a combination of posts from every community that an instance member is subscribed to. For a large instance like lemmy.world that's basically every community, but for medium instances there are various small communities they don't have and for a small instance, the all feed will reflect the interests of the founding members.
