I think the barrier to entry also helps a bit. The folks willing to put up with the rough edges that Lemmy has are also likely willing to participate with the intent of making Lemmy a success rather than just "hangers on" as it were. With a 1600% growth in "active" user population, there are definitely a ton of lurkers, yet. Once it becomes more approachable, we'll see if the community feeling that Lemmy has begins to tarnish and fade as the volume of interaction and content rises.
