> Do people not realize that they're going after Reddit

Reddit is a cesspool and an example of how we're in a post-peak internet like the OP says. If you actually browse Reddit the way the vast majority of people do now (i.e. not Old Reddit that masks the decline), it's crazy engagement-farming patterns everywhere, and not much of a community any more when many comments are hidden by default.

Most people today just like to fire off one-sentence comments; if you seek substantial discussion, you'll often now stand out as a weirdo on the spectrum, and may even draw downvotes and "lol wall of text bro" comments.

Yes, I follow close-knit little subs off the main page. There has been a flow of users away to WhatsApp groups, of all things -- it's that bad.
