I was going to read the site to see what they are up to, but, grumpy old man that I am, I no longer feel the need to push through sites done in low-contrast text. If they don't want it to be readable, I won't read it...
It looks like your rendering (resolution, dpi, hinting? no idea) mitigates the effects of the reduced contrast in a way that mine do not. I'm guessing that's true on their developers' systems as well.
