> that's not "fashion"
It most certainly is.
You acknowledge in your parent comment that you are not the target audience for this site. I assure you that the sort of crowd that's into Linux kernel development by and large prefers web design that other audiences would find archaic.
Conversely, were LWN to have switched to Bootstrap five years ago, or some Medium-like look today, or whatever the next transient fad will be five years from now... their audience would by and large viscerally hate it.
Designer types indulge too much in the fantasy of OBJECTIVE standards for "organized", "hard to access", etc. It's all subjective. Hence, fashion. For people who enjoy working on green-screen terminal applications, switching to a web app version is like giving their workflow a lobotomy. For people who prefer mobile-first minimalist web apps, the reverse is true.
LWN, and it's related subculture, happens to not be your scene. That's okay. But it's perfectly fine to just, well, not comment. Because it is so painfully lame how whenever a deep technical topic comes up on HN, half of the comment section deals with website aesthetics. Hey guys, if some topics just aren't for you, then it's... just... not... for... you... and... that's... okay.
