This partially explains Reddit's staying power. A popular subreddit that hits the point of degeneracy spawns new subreddits that aim to return to it's roots. No-one leaves the platform and the cycle continues.
Both of those features differentiated us from the competitors, and as you aptly point out, it has a nice side effect of keeping people on the platform who might otherwise leave (although that wasn't an intended consequence).
This is done by joining better subreddits, and/or adding them to multis.
Just checked and fortunately scrolldit is back up so my reddit reading will probably go back up too :D
Wait it's.. actually pretty awesome! Still, I wouldn't trade the main UI for it lol.
