Can you expand? I naively thought that a site with markup as simple as HN's (zooming is flawless and it even works without JavaScript) would be very accessible to visually-impaired people.
I do know the tiny text and low contrast make it hard to use for someone like me with older eyes. This is especially true on mobile, where the text refuses to resize in accordance to my phone’s large font settings.

1.25, which is well below the minimum of 4.5
I'm not visually impaired, just in need of bifocals; I zoom HN to 150% and it works fine.
But I am kinda surprised when I turn the zoom off. Even 25 years ago that text would have looked small to me.
I'm wondering how effective non-text would be? Personally, text is my preferred medium for any non-simple communication.
Marshall McLuhan was right to point out that "television" would erode the need for people to read and write.
Maybe it's the best option for some people. Not for me, but I do love an audible book.
In conclusion, I think these other mediums simply lack the iterations that we've put into text over the centuries, leaving text as the clear winner in my book.
It's also great for technique with tools in the kitchen—not learning recipes so much, but learning the right way to process a certain vegetable really fast, or exactly what a proper whipping motion for eggs ought to look like, or how a pro moves the pan on and off the flame while cooking this dish, exactly what it looks like when they deem a certain cooking technique "done", all of that.
What in particular would you wish to have improved?
OTOH the simplicity of the site allows for very easy browser-based scaling, which means I only really think about how bad the text size is once per machine.
