On my iPad, magazine layout via Flipboard is the only way I consume my content now. Because it is non-linear like Google Reader, I actually pay attention to each headline rather than skimming for key terms or phrases.

This layout for digg fits in with casual consumption and discovery, rather than a structure that encourages seeking out specific articles.

I do agree with you that this is a beautifully simple site and will also revisit on a regular basis to see how it progresses.
