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?
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.
