It’s funny hearing about the decline of Reddit so much this past week because I was mostly ignorant of any of it. I’m pretty quick to prune any subs where I wansn’t enjoying the content coming across my feed, so I wasn’t subbed to many of the big subs. (And the big ones I had were very narrow in scope, which helps.)
I guess I noticed the decline in quality in specific subs, but my general experience with quality on-topic comments has remained fairly steady.
Actually, I remember the decline in Reduiquette was really noticeable about a decade ago, but that’s old news.
