Not only is the content great on that site, the performance of it is absolutely spectacular. It's amazing how much people will jump to new fangled solutions when this site is a great example of what a well tuned Rails app can pull off from a UX perspective.
It's cool that it's open-sourced, but I've never been impressed with the content. Even when an article is about a topic I'm interested in, it's hard to get past the Buzzfeed-style "How do you do, fellow kids?" tone.
Yeah, I kinda feel the same way about the content. It's like 'coding, not programming', 'what was your biggest achievement today? Mine was no conflicts ;)' and other silly wholesome comments.
But yeah, the performance of the site is phenomenal.
It's not about tuning, the site just preloads content when you mouseover links, using a background service worker. That's pretty "new fangled" compared to most sites.
Hmm you're not wrong. Re the other comments here about preloading from mouse over events, it's very snappy on mobile too, so there's something else going on as well.
Very gratifying to see it's using Preact, since I've just chosen that for a project over React, largely due to smaller bundle sizes. Another post on HN today about Amp makes me feel it's the 90s all over again, with people shaving kB off here and there - and that's no bad thing!
