I remember there were polls about it, but I cannot find them.
This one user is convinced the users here are literally below the age of highschool. I'm 25 myself and remember seeing people above the age of my parents posting, so I wonder if there's information on the ~population across ages.
I think that's the actual usage, but what I meant there was all of those smug non-comments are are only put in forums to either fill space, feel heard for a bit, or get karma. Stuff like making puns on headlines in world news, or all of those "reddit switcheroo" comments, or even shit like just replying "this!" or "reddit silver." Go on any popular thread on reddit and you'll see hundreds of smarmy snarky empty comments being shouted into the void from people who probably didn't even click the link. It's the forum equivalent of Musk replying "Yes!" to opinions from checkmarks he agrees with.
