I've been here since the post r/CTH ban discord lifeboat days, and I'm still amazed at how dense the history of this community is. There's so much apocrypha that will be lost to time if we don't perpetuate it by putting to writing what each of us remembers personally.
Up until recently, there was this whole-ass over a year long period wherein posts and comments disappeared from search and user histories if they were more than a couple months old. The extensively forked lemmy code Hexbear used just couldn't handle such a large database, we had to return to the main lemmy branch to regain that stuff. I feel this saga disconnected us from our history on this site. Many of the funniest struggle sessions and incidents have all but disappeared from the site's cultural memory as a result.
BMF and their various successors will always be my fav.
Edit: I think my second fav which idk if its even like a thing most people remember but I just remember it in particular.
There was some discussion about communal canteens replacing restaurants in a post-revolutionary society and I remember someone just went full socialism-with-vault-tec-characteristics and started ranting about how no one will have access to any personal kitchens at all, so that a proper and correct single solitary diet could be enforced upon the community.
