I realized that there are alot of inactive communities across the Lemmy and kbin instances. The beauty of decentralization is that we don’t rely on a central instance, if a fediverse instance becomes the central one that hosts the majority of posts, then if that instance goes down, we lose alot. I also suggest posting to small communities on other instances.
I’m not exactly sure how it works, but you can just cross post to your own instance. But if I’m reading tech news, I’m not subscribing to every instance across Lemmy to see it.
If there is a problem with one particular community, users can pretty seemlesly switch to posting on another instance.
