The optimistic outlook on it is that unlike Twitter the quality of content on Reddit relies on moderators who have no official capacity from the site. Twitter is moderated by people who are paid at Twitter, so moderators leaving the sub (and taking the curation the users enjoyed with them) is much more impactful.

Twitter is about people, Reddit is about content.

Do you remember any nicknames or any famous Reddit users? I remember the story about the poop knife but not the nickname. I remember on lemmy the 3 day no poop challenge but not the nickname.

I can't remember how it was circa 2010, but it feels like it's harder to "kill" social media sites now.
