I feel like there needs to be instance aggregation for Lemmy to really work in the long run (and really this is probably true of the fediverse in general). Having to add communities across multiple instances, and not being able to browse them in a centralized way, really detracts from the experience. On Reddit, I subbed to the stuff I wanted and just lived off that feed. With Lemmy, I feel like I have to stay in unfiltered view to get anything of interest--the fragmented niche communities are just too limiting.
