In a way, Reddit was a prelude to nostr where anyone could post anonymously. The most important thing about Reddit though was the segregation of content, if I wanted to know something about a specific topic I could almost guarantee there was a subreddit for it.
It was also a great case study for self moderation, none of the moderators were compensated in any way but the content was good.
I wouldn’t have left if they had kept everything as it was but they had the API war and nuked all of the third party apps. This is why I like nostr
