This absolutely sucks in every way. The icons suck, they aren't clean, clear, flexible, or well made. The styles suck, they are too basic to even be useful - we can all put a 1px border or border radius on an element. And it's not innovative in any way, web designers have been doing this for years, except with actually good icons and css styles.

I'm genuinely surprised that this made it to the front page of hacker news. That being said, I still think Nick La is a great designer.
