Correct me if I'm wrong. I read ActivityPub standards and dug a little into lemmy sources to understand how federation works. And I'm a bit disappointed. Every server just has a cache and the ability to fetch something from another known server. So if you start your own instance, there is no profit for the whole network until you have a significant piece of auditory (e.g. private instances or servers with no users). Are there any "balancers" to utilize these empty instances? Should we promote (or create in the first place) a way how to passively help lemmy with such fast growth?

Every server just has a cache … there is no profit for the whole network …

I wouldn't say that caching is no profit. Yesterday there were several times when lemmy.ml was struggling or effectively down for some people, but despite complaints over there I could read lemmy.ml communities just fine through my instance. Caching meant that I was isolated from the service interruption, and the lemmy.ml server was isolated from my contribution to its load.

Well, lemmy.ml still needs to serve you the content the first time in order to cache it. And since you're the only person in your instance, you're the only person benefiting from that cache. So you're still exerting at least the same load as if you were browsing lemmy.ml directly.

As I said, there is no profit from empty instances. Of course, the federation itself is good and fail-proof in this way. But if nobody asks for this cache, it's just an Internet Archive of a sort.

It only takes one user for an instance to not be empty. Every bit of decentralisation adds resilience to the whole. But more decentralisation adds more resilience, so let's try to spread out the communities and users.

I just spun up my own instance as well and it does feel a bit like I'm just pulling from the biggest instances and feeding my own without really being able to give much back.

I have my own Lemmy instance running on my home server, but I'm here. "But Bizzle," you may be asking yourself, "why go through all the trouble of configuring your own instance just to wind up on Lemmy.World anyway?"

I'm glad you asked! And the answer is that federation only fetches parent comments. I'm glad Lemmy exists, and I'm going to keep using it, but we need federated sibling comments for this to actually be good, in my opinion.

EDIT: I actually couldn't have been more wrong.

I would be happy if my locally posted comment showed up on lemmy.world at all :-) (If this one does, maybe I was just impatient with the initial sync or so)

EDIT: Nevermind, I was too impatient :-)

you mean do something like blockchain ?

It's a bit worse than that actually. I'm now seeing several communities with exactly the same name that originate on different servers - so clearly Lemmy doesn't have a rule about duplication once you cross a server boundary. That's going to get unwieldy quite fast particularly if, I dunno, "Aww" gets popular on two separate servers at the same time - I guess I'll have to subscribe to both...

[–] c0mbatbag3l@lemmy.world 1 points 1 year ago

That's true, and the point I guess. You sub to all relevant communities and the overlap isn't an issue because it's different communities with different instances making content with others interacting through federation. The "subreddit" is diversified to the top communities in all of the highest subscribed instances. It's just the nature of the beast, but once you find all the top comms it probably doesn't seem so bad.
