There are many lemmy instances in the world, but currently most people are using lemmy.world. This is why everything has gotten so slow.
You don’t have to delete your lemmy.world account, but check out https://lemmy.fediverse.observer/map it’s a geo-based map of lemmy instances – explore stuff nearest you, pick one, sign up, search , subscribe and begin interacting with your favorite communities. It’s easy, free and it will be faster. Try it!
As far as I understand, your instance is only aware of a community on another instance if at least one user on your instance has subscribed to that community on the other instance. Perhaps that’s what you’re experiencing?
That’s interesting.
I’m fairly new and I’m not seeing a lot of chatter about the limitations of Lemmy / other fediverse applications.
I don’t suppose you can point me to where you learned this and/or other information on how information is shared between instances?
Sure, I also have been trying to learn about how Lenmy works. I haven’t yet found a comprehensive overview that details everything though.
