How does federation work with the "subreddit" model?
How does federation work with the "subreddit" model?
Hi, I'm new here, so sorry if this has been asked before.
I understand that Lemmy is supposed to be like a decentralised Reddit, but I've got a question about this; on Reddit, there is only one server, with subreddits on it, so there is only one r/Music, only one r/AskReddit, etc.
However, on Lemmy there are many servers; would this lead to a situation where many servers have repeats of the same popular communities or does this not happen in practice? Is there a good way for me to find communities across all federated instances? Thanks :)
You're viewing a single thread.
- In Lemmy, a
communityis the equivalent of a Redditsubreddit. - Each community has a home server, like this community is
[email protected], and you generally identify the community by its full name this way... including the server part. Local communities that exist on the server where your account is may omit the server part, but they are still homed to a server... it just happens to be the one your account is on. - Federation makes it possible to participate in communities on other servers. Like your account is on
lemmy.blahaj.zone, and mine is onlemmy.world, but we're both able to post to this community which is homed onlemmy.ml. Not every lemmy server federates with every other lemmy server, but in general... federation makes the home-server of a community somewhat irrelevant.
Each server COULD have its own duplicate community, and in some cases that happens. Like there is both a
[email protected]and a[email protected]. It could also be possible to have two competing communities on the same server, like it would be possible to have a[email protected]as a third option. The end result isn't all that different from Reddit where you can have different subreddits with overlapping topics. In most cases, I think you'd expect one or two of those communities to get most of the subscribers and posts... just because mostly-empty communities aren't very useful. But absent major drama that splits a community into factions... most people would gravitate toward an established community even if it was on another server rather than start a new local community with no one in it.It kinda bothers me that communities are formatted like that instead of their actual http URL. When out of context, this is converted into a mailto: link, whereas using the http URL would result in a link I can click to actually get to that community.
I'm a little fuzzy on the difference, but I think you CAN use
https://lemmy.ml/c/lemmyinterchangeably with[email protected]... though yeah... the latter seems to be the thing that's displayed everywhere and it does get handled in a funky way by things that understand mailto.
