Sturgeon’s Law applies: 90% of everything is crap.
Reddit’s value has never been in the “average redditor” or the “popular subs”. The real value is in the niche tail of communities and the fact that they have such a massive amount of people that even if “only” 10% of their users were decent people, it still meant that they had enough decent people to talk with something to contribute.
All in all, this is just to say that our problem should not be about “Reddit users”. Our problem should be with Reddit management. The threadiverse is still incredibly boring. Things here are mostly meta-conversations and there is little to no original content here. The way to solve this will be by bringing more people here. A lot more.
