HN always moans about reddit, they've moaned about it for near a decade at this point, it still just grows bigger.
Now, are those the people you're talking about? No idea, I haven't seen who you're referring to and it'd be case-by-case. But point being, the existence of "ex-Redditors" isn't necessarily a bad thing.
but I think they'd decline hard if they turned off old.reddit e.g now.
I wonder if this has anything to do with the "downvoting comments I don't like" phenomenon that seems to have taken over HN these past few years.
I own quite a few subreddits. Maybe I'm a future power user.
The old guard typically dies before the new generation can thrive. Until they leave they tend to actively gatekeep keep potential competitors out.
I am fine with hearing "Maybe you will finally get to build your own garden, at last, Doreen." God knows the past decade has been pure shit for my online social life, which stands in stark contrast to when I routinely had real friends online, met them in person, got meaningful help with my health issues, with raising and educating my kids, etc etc.
