Is it just me who finds the serif font used in this website too narrow and hard on the eyes, even on Retina displays?
Design trends are cyclical, but clean and simple design can be timeless. E.g. Helvetica, Braun, etc.
This uses a classical serif font with minimal formatting and colors. It is inspired by a simple book layout, which wouldn't look out of place in any classy publication today, from a hundred years ago, and likely a hundred years from now.
There's not much here that can "age", or that we can move on from.
