Interesting site. At first I thought my browser was somehow set to 250% zoom. So then I zoomed out to 50% but the font sizes are still as big as they were at 100%.
Weird. Apparently they decided to (ab)use CSS viewport units everywhere just to jump on the cool kids bandwagon, completely breaking browser zoom functionality. This is not what viewport units are for. The site is also nearly illegible at 610px browser width because of it.
