I like it. I dislike the weird stupid half cut header. (Because it looks like there's a sticky header, but it's not a sticky header, and it feels like the font is broken. That's a dissonance that I don't get from print-typography experimentation.) But I like the "big" (readable) fonts. I'd probably make the body font a tad bigger, but I guess that's just me. I wouldn't have a bright white background either, but again that's mostly me. It's nice when a website needs a minimum of tinkering to make it readable.

There are (as they say) a few oddities. The link on "Why are links blue" is not blue, it's black.
