I second red reader. To you SNR point, I think that is entirely due to the communities you join and how you manage it. Unsub from all of the default subs. They are all garbage. And any that gets beyond a certain size will inevitably fall to low effort reposts and click bait.

Reddit is best as a platform for effortlessly making focused special interest forums. In the past these would have required a PHBB instance and hosting, would have nonexistent SEO and would be almost impossible to find. But they would have some of the best content the internet had to offer.
