Not really, there are a bunch of small reddits that really is a good source of information and community. E.g. r/leathercraft, r/learnmath, r/godot and so on...
The sub also needs to get big enough to get out of the "Facebook group" mentality, and have at least one competent mod that keeps it from turning into memes and shitposting.
It's a tricky balance. I've been in small (~sub 500) subreddits that are worse than larger ones just because the mods don't enforce any posting requirements.
