I do wonder how HN specific this is? Every site that has a quirky design or attempts something new gets absolutely blasted by surly people. But then someone posts a funny GeoCities style bootstrap theme and everyone goes on about how they miss when sites had a quirky touch?
When I “blast” a website design, it's for practical reasons, not because I dislike the design. Since I mostly read HN on my phone, every website that is slow, laggy or unreadable on mobile just stands out negatively.
I really think it's just simply about scrolljacking and not anything deeper. The GeoCities style sites have normal scrolling and the F1 site has hijacked (and very bizarre) scrolling. If your site hijacks the scrollbar then you will get complaints on HN. Keep it in mind and see how many HN complaints you read that are actually just about scrolljacking. I think readers here love quirky websites as long as it doesn't mess with scrolling.
