I joined reddit more than 14 years ago, before subreddits, when it was written in lisp and top posts were Paul graham essays and Joel on software. Today HN is the place for this kind of content. When digg died there was a fear what their user base would turn the site into. I have no issues with the design but probably because I’m mainly on my mobile. What did change for me though was the amount of toxic people in almost every subreddit I frequent.
http://www.paulgraham.com/re.html suggests the world may be getting “more toxic” (fragmented + interconnected), rather than some underlying force (“It’s because Digg’s user base invaded”).
