I think the split between into three subreddits was necessary after SpaceX became too popular. Of course it was more fun when the community was smaller and more focused. But at a certain point, the influx of new users that would contribute with the same set of basic questions/ideas/memes (“Why doesn’t SpaceX just …”) was too large. /r/SpaceX had to act as a restrictive filter into the community.

Well, we certainly won’t need any of that here for quite some time, I assume …
