This site is currently struggling to handle the amount of new users. I have already upgraded the server, but it will go down regardless if half of Reddit tries to join.
However Lemmy is federated software, meaning you can interact seamlessly with communities on other instances like beehaw.org or lemmy.one. The documentation explains in more detail how this works. Use the instance list to find one where you can register. Then use the Community Browser to find interesting communities. Paste the community url into the search field to follow it.
You can help other Reddit refugees by inviting them to the same Lemmy instance where you joined. This way we can spread the load across many different servers. And users with similar interests will end up together on the same instances. Others on the same instance can also automatically see posts from all the communities that you follow.
Edit: If you moderate a large subreddit, do not link your users directly to lemmy.ml in your announcements. That way the server will only go down sooner.
This is how I am understanding it. Please correct me if I am wrong.
I'm going to use Reddit as an example, since we all understand that...
So the way I understand this is that backbone is now the whole of the internet instead of just reddit.com.
Each instance would be somewhat akin to a self-hosted subreddit. We can reach any sub from any other sub, since the backbone is now spread across the whole internet instead of just reddit.com.
These subs (instances) are also like old style BB forums in that there can be different categories (communities) hosted by that instance, but those are also still visible across other instances.
So basically people who are making communities here are making a sub in a sub (in Reddit terms).
Do I have that correct?
Mostly. I try to think of instance as not a subreddit but a loose collection of them, like a multireddit.
What is kind of nice, in my understanding, is that text content is replicated across federated instances when a user is using both. So if you're on beehaw and comment on lemmy.ml, both of these servers will have your comments. That's already providing slightly more redundancy than reddit.
