Weird. Naturally it works beautifully on mine with two different browsers, though I'm not in the habit of using the page-down key. I'll have to investigate that one further, I guess.
Works as it should for me too, on desktop Firefox here. Site design and fonts are quite nice. People on HN often lament the death of the "old web", but when we do get a site handwritten and with a personality, they turn around and say it is not usable. The strength of humans is our flexibility. We're not computer programs that throw an exception the moment their api is violated and an unexpected input happens.
