I can't even begin to fathom why anyone would want to train an AI on this corpus. Reddit isn't a social media site. It's not organic. The vast majority of the content of the site is created by just a dozen users. (Those people have to be doing it as a full-time job.) At the end of the day, Reddit is a top-tier porn site, with just enough "social" thrown on top to give people something to read between wanks.

I see a lot of people express that they get value out of the technical subs, like finding answers to programming questions there, but for the life of me, I can't see it. Ninety percent of the time, there's not even a bad answer. If there is, there are narcissists and sociopaths pedantically arguing about it. If Reddit has captured a particular search, and is taking up the first several slots, I will add "-site:reddit.com" (and YT) to my terms. I keep wondering what I'm missing, and it's starting to feel like I'm being gaslit into believing there's something of value there with internet-wide astroturfing.

And the same thing goes for any other sub, too, from mechanical keyboards to so-called "audiophile" gear (don't get me started) to various specific gaming "communities" I've tried to participate in. Contrary opinions, no matter how delicately expressed, are run out of town on a rail. There may be a useful comment now and again, but they are drowned by rudeness, ignorance, stupidity, pedantry, and -- most of all -- gatekeeping. Do I sound bitter? I'm bitter. Good luck with that.
