I feel like we use reddit in entirely different ways. I don't use the front page. I'm not subscribed to any main subreddit. I use subreddits to find information about my interests: Individual game subreddits, Financial information, Product reviews.
Does everyone who has strong dislike of reddit stay subscribed to /r/news and /r/worldnews (and others)? I know those subs ruin my feeds and my mood. Otherwise, I don't see how reading something like /r/factorio can decline one's mental wellbeing.
