I recently setup a new Lemmy instance and was surprised when my feed was mostly empty. I've since learned that a key part of Lemmy's federation is based on a user from your instance subscribing to communities on other instances. Only then, will your instance pull in posts from the subscribed community to your "All" feed....
Thanks for the tip, I updated the link! And I'll work on drafting some more text about the implications of subscribing to everything.
An instance hosting lots of niche/unpopular communities is going to be sending thousands of copies of every post/comment off to instances where no one is going to read them.
The rate a small instance would need to send off copies would be tied to the frequency of posts to the community, right? I'm interested in aggregating the lemmyverse, but wouldn't want to overburden other instances in doing so. Although, honestly, I'm more worried about overburdening my own trying. Were you suggesting that it might be rude to subscribe to a community just for discoverability?
So far the hosting requirements seem moderate, although I'd image if more people browse the feed the CPU and database reads will spike. I'll keep an eye on them. I'm not sure if this project is feasible/needed yet, but I thought it might be interesting to try. And if ever help, then I'd imagine during the start of a bunch of new instances.
