A few years back Notion was excellent modulo a few small UX things that could be improved.
Now those small things still haven’t been improved but there’s way more clutter worsening the UX notably over time.
But if this is what it takes for someone to generously share so much information with us for free then I really don’t care if I have to wait a couple extra seconds for a page load or if a tab takes up 600MB of RAM. I know this thinking makes the web purists angry, but the majority of people who visit these sites to learn aren’t going to be impeded or even bothered. Even on my older iPhone on non-5G cellular it loads in a couple of seconds.
Not everyone has a fast device also.
On the network side it makes ~650 requests.
That's an exceptionally resource hungry way to load the content.
Hit the back button whenever a page says JS is required, unless you want to read it badly enough to wait for it.
The web is much better that way.
