This is off-topic, but his blog is not only readable but has a very distinctive design/feel to it. It immediately reminded me of these two fantastic articles that have appeared on HN before.
Agreed. I particularly liked how the section heading showed up on the left only after you had scrolled to that point.
Yeah, they're very interesting. I have to say though that I find the way they flick in and out of existence as the section header itself moves on and off screen a bit distracting. I'd have gone with something a bit more like iOS sticky scroll list dividers--on a lot of iPhone list widgets, if there's a header in the middle of a scrolllist, it sticks the top of the screen as you scroll past it (until you hit another one). Not sure how exactly you'd do this in a sidebar tho....
The first thing I thought is "what rhythm!". Steve, thanks so much for making the whole deal opensource - this is exactly the sort of design I've been gravitating towards. I especially love the main blog page and lack of pagination on anything - it feels like the first blog I've seen that actually gets it.
