I saw this post which is completly unrelated to me making this post btw.
The way you sync communities makes a lot of sense when you only want to subscribe to certain communities, but when you want to see what's going on lemmy it's bad. When I scroll through all can't shake the feeling that I could be not seeing some interesting posts. This is not only a problem that small instances have. I checked lemmy.ml and it had some posts missing from all: new that we can see. But this could also be because of defederating.
This problem is even worse with nsfw communities. They don't show up when not logged in, so looking on other instances is useless. And the community search site in the sidebar doesn't work well and doesn't show nsfw, although lemmyverse.net works fine.
So what I'm saying is who on this instance is going to subcribe to furry porn, jk
Yes I am concerned about it and we will probably miss some great posts. I don't want to sugar coat it. There is not really much we can do as instance admins.
