How do the different federated software interact with each other?
Hello everyone.
I am relatively new here on Lemmy, and the Fediverse, and there is still a lot I am trying to learn.
I think I understand the general theory of how the different instances and communities work here on Lemmy, but I'm struggling to understand how the different federated software interacts with each other.
For example, I understand that it is possible to follow a community, commenting on its posts, or a user subscribed to Lemmy even from Mastodon. Similarly, it is possible to follow an author on Write.as, again through Mastodon.
What I wanted to understand is what software in the Fediverse interacts with each other, how, and how do you get them to interact.
I hope someone can help me better understand how things work, as I find the idea of the Fediverse absolutely fascinating, a real breath of fresh air in the modern Internet landscape.
So far I have understood it.
I meant the question in the most practical way: how can I make different software in the Fediverse interact, and which ones can interact with each other?
For example, since it is possible to follow a Lemmy community on Mastodon is it also possible to do the reverse and follow a Mastodon user here on Lemmy? Or is it possible to follow a Peertube channel here on Lemmy?
I'm asking myself the same question. Do I need to make an account for every platform/service I'm interested in, or can I just use the same account for everything?
From what I've understood so far, the ActivityPub seems to support the integration of different platforms in theory, but there is currently no client software that can show me an integrated feed with everything.
You can create an account on a single Lemmy instance/server, and use that one account on that instance to subscribe to other communities on other instances. Those communities then show up in your subscribed "feed" on the server where your account is.
You can see all the posts from all the communities you've subscribed to on your feed on the instance you signed up on, without needing a client app, or you can install one of a few apps for either Android or iPhone. On these apps, you sign into your account by providing the address for your "home" Lemmy instance, and then enter your username and password for your account on that instance. Then you'll see your feed and everything you've subscribed to.
You can post on any community on any server you've subscribed to using that one account, and your home instance will sync your posts to that community in the same way it syncs posts from your subscribed communities to your home server so you can see them when you look at your feed.
