My sense (from 10+ years on reddit, 2 of which spent moderating a somewhat large/active subreddit) is that there’s a “geeks MOPs and sociopaths”–like effect, where a small subreddit can (if it’s lucky enough to start with one) maintain a distinctive identity around the kernel of a cool idea, with a small select group who are self-selected for a degree of passion about that idea.
But as the size of the group grows it gradually gets diluted with poor imitators, who are upvoted by a general audience who are less discerning about whether posts are in the original spirit of the sub. Which also potentially drives away the original creative geeks, when the idea feels played out and isn’t fun for them any more.
That and large subreddits needing to fight the tide of entropy, against being overrun with the same stuff that fills up every place that doesn’t actively and strenuously remove it—the trolls, bots, spam, and political bickering.
