Just in case any of the authors read HN, I'm getting a pretty crazy rendering bug on this page, where a bunch of the contents are redrawing up and down by a few pixels. It seemed to go away with resizing the width a few times, but I didn't look into it too hard. My page width was probably small on first draw. Incredibly distracting though and hard to read with the text moving. Using latest chrome, and it occurred on more than one page refresh. I didn't dig in beyond that though.
I'm seeing the same thing on Firefox on Linux. It almost looks like the page scroll is jiggling up and down a tiny amount constantly when it's supposed to be stationary.
