This is getting off-topic, but the US is like the motherland of telling other people how they should behave. Look up any of the "public freakout" videos, they're 80% each side trying to explain why what the other side did was wrong, all the while not realizing that pretty much nobody cares about their opinion and is just there to watch the drama for a few minutes. Every single "Karen" video is full of self-righteousness, that's what makes them so hilarious (until you get bored, which happens rather quickly).
Whatever else was true of the early years, when internet use was a niche thing it wasn't representative of broader US culture sort of by definition. Now it is, or at least much more so.
Your point is well taken, but ephemeral nyms aren't new. I actually like knowing they are out there. You need to evaluate what you read on its own merits. And there's an aspect of rebelling against the logic of accumulation.
They did exist, but a lot of us filtered them out with our newsreaders.
I don’t have unlimited time to read comments so I prioritize ones from the patio11, cperciva, and ChuckMcMs of the board. Not because who they are IRL but because a history of posts I found interesting, informative, etc. makes it more likely the next one will be too.
