Community isolation is still a big problem. Federated services like lemmy will never reach critical mass until owners start limited communities to force more user interaction, and cross posting becomes more streamlined. My favorite proposal as a solution is to allow mods of a community to subscribe to another community, and allows it to synchronize posts and comments.
Yeah! Here, no one gets paid when someone else wants to profit off of all the free user generated content. Wait, what was our goal again?
