A brand new instance on the fediverse doesn’t initially know about any other instances. Only when someone searches for a community@instance does it then go talk to that instance and subscribe to get posts/comments etc.
Maybe you can help me. I joined under Lemm.ee. I want to subscribe to c/[email protected] but it doesn’t show up on my search list. What do I type in to find it?
Search [email protected]. Make sure to include the exclamation mark. Give it about 30 seconds and search it again, and the community should appear, and now you can subscribe.
Thanx for the reply! For some reason, I didn’t get the results in my search bar via the Connect app, but I was able to subscribe via my desktop. Not sure what the difference is, but at least I can see my working cats now :)
I’m also not sure what the difference is, but the desktop app does seem to be better about initial federation. Glad you were able to get your working cats, feel free to ask if you have any other questions
Same here. I understand the whole notion of how an instance is able to “see” communities on another instance on the fediverse. But I don’t get what these kinds of website do differently to see all communities on all instances and why instances can’t do that directly.
Appreciate the clarification! I’ve been trying to wrap my head around how the fediverse works but I’m far from a programmer so some parts are still a bit confusing to me.
Is it just a different approach to reach the same goal or is there some inherent limitation to how the fediverse works that prevents instances from using crawlers?
The Fediverse (Lemmy/Mastodon/etc) is based on a following/subscribing model; each instance only “sees” what it’s users are currently following or subscribed to. This keeps storage and systems usage lower since each instance doesn’t need a complete copy of the entire Fediverse. This third party is more like a web crawler like Google, just crawling from instance to instance and saving the data. Hopefully in the future Lemmy could add something like this discovery feature, maybe something like Mastodon Relays, to aggregate community lists, but it would definitely put more strain on each instance.
I dont get why a third party site can see more of the fediverse than the fediverse can.

It sees the same information, just aggregates it differently I guess.

Wow, thank you so much for taking the time to write such a detailed explanation. It really clears up a lot of what I was confused about.
The community across the board on Lemmy has been so refreshing compared to the last few years on Reddit or any of the alternatives I’d tried before.
They explain it on the project’s GitHub:
And why is it using this method, and not the third party sites method that sees more?
