On a computer I see no benefits from any of the redesigns compared to old.reddit.com. I work a lot with Typescript and also React myself, and I love the language, so it's not because I dislike that sort of thing, but I think a list of links with comments just works better without being put into a virtual DOM or even just JS. HN is the perfect example of that, there has been a lot of hobby JS frontends from people, but they all work worse than the real deal and somewhat hilariously they work better than reddit's professional attempts. Now I get why reddit wants to move away from the page-reload. They want a lot of the SoMe interactivity, like their silly chat and so on, but I'm not sure who would ever want a Facebook with total strangers instead of people you actually talk with. I sure don't.
There were posts on reddit about the most toxic work culture there i remember with drugs and bizarre politics straight out of some san fran sitcom.
And some quite funny posts on just how grotesquely "my first react project" the whole code base was, and still is. These people are absolutely clueless. They nuked the whole "new reddit feedback" forum with posts pointing out just how bad the whole thing was, like pulling tens megabytes of starter boilerplate in production and loops with script loads inside of them that could grind a powerful computer to a halt.
