I think it's because reddits user base has significantly decreased in age. I have been using it since late 2012, which even then I felt like a late adopter. The content on Reddit back then was like a more ”normie" version of HN and slashdot. It had good articles consistently with maybe 1 or 2 default meme subreddits. Then Reddit started cutting down content it didn't like and now it's just a leftwing cesspool of antisocial, antiwork rhetoric. It's not even worth posting or commenting because if your comment veers slightly off course, instant downvotes. Not to mention the monetizing of posts with stickers. It's just turned into out of touch people who glorify mental illness imo.
