Lemmy is an improvement on Reddit, but imo not by much. There really is no innovation on the fundamental concept of subreddits/communities. The issue with Lemmy is that I've come across so many promising communities that quickly die off after the initial spurt of activity. I wonder if there is a better organic way to grow the "online discussion" from some form of general cespool, that can segementize only later when those needed segments (communities) emerge naturally.
