I judge the quality of the subreddit by the signal-to-noise ratio for posts, by the insight and intelligence of the comments, and by the extent to which is provides content that cannot be found through simple googling. Most knitting subreddits do not have this. Again, do you have specific examples? I don't know why you think my opinion of r/SpaceX is driven by some obsession with rocketry. I am much less interested in SpaceX than in a dozen other hobby topics, but that subreddit stands out in the objective quality of the moderation and community. Likewise, HackerNews is one of the higher quality places for discussion on the internet even though I do very little programing.
