Reddit is actually undergoing a rewrite for their web frontend, which now heavily uses web components using lit. You can try it by accessing sh.reddit.com or using reddit without logging in.
Reddit is a company that seems to be chasing trends not understanding what they are.
I fully expect their site to become the same mess as their previous React re-write. I mean, it already is. There are people arguing that 2 seconds to load text and images is fast, actually: https://twitter.com/addyosmani/status/1678117107597471745 ("Engineering Leader, Google Chrome"). And they already load 109 JS files to display it.
Wow, this is actually way faster than new.reddit.com. I may try it out over old.reddit.com. There is obviously a difference in that it emphasizes media content with large cards instead of the more dense old.reddit.com but that is preferable for some content. I'll have to see how it feels with more use.
The only major problem I noticed is that the "comments" button wasn't a link so you couldn't open it in a new tab. I don't know why web devs hate real links. They think the only think you can do with a link is click it to open the target page.
