So if I have an account on lemmy.world, can I post on lemmy.ml without creating an account there? If not, I don't understand how all the instances "communicate" if I have to have multiple accounts to interact with each one.

A lemmy.world user can make posts on lemmy.ml and vice versa. You don't need to be a member of the one you post to, but you need to be a member of any one of the federated instances. You can even start your own instance and be the only member on it if you like.

George, who uses gmail ([email protected]) can send emails to onno, who uses outlook ([email protected]).

George sends the mail via gmail, which sends the mail to outlook, which sends it to onno.

This is only possible because gmail and outlook share the email protocol. They are "federated".

If a lemmy.world user submits a comment to a lemmy.ml thread, the user sends it to the lemmy.world server, who will pass it along to lemmy.ml, which will show the comment to lemmy.ml users.

In theory, this should keep everything in sync. In reality, mismatches in protocol implementation and differences in blocked users/instances, create different views on the same thread when viewed from lemmy.world and lemmy.ml

For example: lemmygrad.ml could be blocked/defederated by lemmy.world, while lemmy.ml is still federated to both. When viewing a thread from lemmy.ml, you can see content from both lemmy.world and lemmygrad.ml, while the views from lemmygrad.ml and lemmy.world lack each others content.

I’m not understanding this either. Do I see posts made by Lemmy.ml when I’m Lemmy.world? If I subscribe to a group like memes can people with a Lemmy.ml account also join it? Or is their meles group a different one?

I've learned a lot since I first posted lol! So first I started filtering my front page by "all" instead of Local, which will then show other instances. To subscribe and post to another instance's community, you can search [email protected] in your instance's search to subscribe and post. It seems difficult and clunky to me to discover and subscribe to other communities, unless someone has an easier way? But to answer your question, AFAIK, yes lemmy.world's meme community is entirely separate from lemmy.ml's, but you can still subscribe and post to either one.

Thank you very much for explaining this! So I’ll search the other communities. Or is it smarter to also join lemme.ml? Since I’ve got no idea which other communities ml has. Or does ml have a homepage with all their subs on it like lemme.world has that I’m able to browse?

It seems like lemmy.ml is larger and more popular, but right now they're having server issues. I tried to make an account but couldn't, so I'm just sticking to world for now. If you just go to lemmy.ml you'll see all their communities and then you have to search lemmy.world to subscribe to them
