I also agree the front page subs were mostly filled with shallow fiction, but there was definitely good stuff going for Reddit before Spez f’d it up. I’d say the magic was in the small and niche hobby/fandom subs, the communities in a lot of them were truly unique and vibrant.
I think what’s scaring a lot of people off is moderation. I’ve considered creating a few communities myself but I’ve never been one for managing. I try to do my part by interacting with communities that have been created and driving activity. Huge kudos to those who are founding these communities though.
