This might be an ELI5 question but it has to do with Lemmy
So I immediately jumped into lemmy.world and created an account and community here. Then after further digging and instance exploring I found lemm.ee and found it to run much more fluid and faster and gave me a better user experience. So, I then created an account and the same community on lemm.ee thinking I had to choose one. I have this weird feeling one server will dissolve or be obtained by the other and I will lose things, is that even a thing? With the lemm.ee account I got a lot more action in my community. Should I keep things active for a while or is it safe to choose now? I'm kinda tired jumping back and forth. Thank you internet people.
Pick whichever one for the account you’ll use; and you may want to join from that one account both the communities you created. Remember any account can join any community of any instance.
it does not matter the instance where you create your profile or community, all are federated.
small instaces run better because lemmy is (not yet) good at scaling.
