I would agree that I love HN's minimalist approach, but the end game for HN and Digg are vastly different, aren't they? I think the perceived value of rolling out new software is that Digg had hoped it would draw in more uses and entice existing users to become more active. If you're running a website that is largely user generated content and is also stagnant, how do you inject new life into it without adding new features? I'm genuinely curious.
