I get the idea of instances, like you can make your own and this is good for privacy. But some lemmy instances are much more popular and this in fact makes it another Reddit. If there are separate instances for niche topics, why not make it another community inside a larger instance?
This is one of my favourite things about lemmy. It’s resilient. You can always find new places, new communities, new posts on different instances. It really feels like traversing the web like in Reboot. I like so many instances.
