As a new reddit exile, I may be misunderstanding this.
In theory something like a !gaming community could crop up on multiple large instances, especially during the mass exodus while instances are getting hammered with spikes in volume.
If that’s the case, we’ll have fragmented communities across instances. Is there any way besides subscribing to each of them to combine them into a sort of multi-reddit type aggregation? Or is this considered a temporary (albeit important to adoption) problem during the crazy stages?
No idea honestly. My best guess would be that browse.feddit.de hasn’t cached those communities yet if you just recently created them. There’s options to turn on/off different instances in the sidebar, and it looks like feddit.de is on by default.
