What you describe as "noise", others would recognise as "culture".
Edit: Hopefully this doesn't seem like I'm creepily stalking online strangers. I just notice their usernames a lot!
Reddit is a hellhole. I lived on Lemmy for a while and its really just as bad.. maybe worse because you have to deal with the insufferable open source hardliners.
For actual information, hacker news, rss feeds, podcasts, and medium posts are the only things I can stomach anymore.
