Im joining in on the reddit ditching thing, and was kinda worried at first that i wouldnt be able to like use it the way i did reddit as it feels like a whole new place, but after engaging with posts and people and actually being a part of lemmy rather than being lurk mode all the time i was pleasantly surprised with how easy it is to become a member of the community, theres a reasonable amount of subs (or whatever the other word for em is) that fit my interests, enough linux content and shitposting for my liking, and the overall random posts made by people equally fed up with Leddit. (also i admit i used reddit a little cus there was this post on the fedora sub showing how to fix a sound issue i been having after a recent update)

That's what I meant, I think they should make it so that all communities show up by default on the community list page.

Also just so I understand what you're saying, are you saying that I could intentionally sabotage a server just by subscribing to a lot of communities, which would cause the All page to use a ton of resources whenever people look at it?

On a tiny instance with insufficient resources, maybe. But it's not so much a problem for one person to decide to subscribe to a lot of things. It's more that you have to be careful about eagerly shipping useless messages around big federated/distributed networks. Imagine a world where Lemmy is very successful, and a network of 10,000 instances federate with each other but maybe 9000 of those are tiny personal instances. If one of those servers has an unpopular sub, there's a BIG difference between shipping 50 copies of a post made on that sub to the servers with users that care... vs shipping 10k copies to servers where mostly no one cares. Then multiply that by the potentially hundreds or thousands of posts on unpopular subs across the whole network. It's very easy to ship around millions of messages that no one reads. Good federated designs MUST minimize this.

So if you want to intentionally sabotage the network in the way I'm describing... then you'd set up thousands of lemmy servers and configure users on them to subscribe to everything. People would probably refuse to federate with you and the bad thing would never happen... but yeah... thousands of servers could generate a pathological amount of replication load on the servers hosting active communities.

Hmm interesting, thanks for the explanation.
