this is an interesting question i’ve had banging around in my mind since well before Reddit’s implosion (and Discord’s enshittification), but which seems really worth asking now.
you can’t blame Reddit and Discord or their imitators entirely for these going out of style, but they’ve sure put the dagger in a lot of remaining ones, and i kind of wonder if they’re just in an irreversible and terminal decline a la USENET. i can only name two or three i even consider checking anymore, and i’m not sure how sustainable any of those are long-term.
I’ve actually noticed myself doing this by instinct as in the last few months I mostly read Reddit comments sorted chronologically. Part of that is because of the hivemind problem in certain subs, which frankly is even less tolerable the more trivial a subject is, as in, for example, subs for fans of a certain artist where other users jump to downvote people who dare say that not every thing the artist does is perfect. And what’s even the point in discussing things if everything is “how good this is”, “how amazing this is”, etc.?
