He mentions Substack, which is maybe the most egregious example of bloat I regularly encounter. Like I cannot open Scott Alexander's blog on my phone because it comes to a crawl.

>I'm much more of a backend person, so take this with somewhat of a grain of salt, but I believe the issue is with how we're using react. It's not necessarily the amount of content, but something about the number of components we use does not play nicely with rendering content at ACX scale.

>As for why it takes up CPU after rendering, my understanding is that since each of the components is monitoring state changes to figure out how to re-render, it continues to eat up CPU.

They know—but they do nothing to fix it. It's just an impossibility, rendering all those comments.

I don't access this site a lot, but I remember until very recently they had other front-end, it worked great. Honestly, I think they will follow the path of medium.com, and start to make the user experience worse and worse.

It's a site where people post text, a few images, maybe 1 or 2 videos per post. It shouldn't be complicated.
