This is a good "I am Very Smart" candidate which surprisingly doesn't seem to have an active community here on Lemmy yet...and I might be just fine with that now that I think about it. It seemed like half the posts there on Reddit either were mean spirited, called out the wrong side in an argument, or were actually smart.
Yeah I don't think anything of value is lost if we don't recreate all they bully subreddits.
They're unhealthy for their subjects, of course, because imagine seeing a post you made when you were younger on one of those subs and reading all the comments about how terrible a person you are
But they're also unhealthy for the subscribers and readers - rage scrolling will fuck you up
maybe lemmy would be the drink from star trek: the original series (pilot episode "the cage")
That drink had enough of every nutrions the species needed and tasted like what the living thing wanted (one that fits all)
But it is not a drug
You can watch the episode if you like but the special effects really fit 1988 but i think how the characters are played is way more modern that 1988
