Most likely this site: http://portableapps.com/ which is running D7 <meta name="Generator" content="Drupal 7 (http://drupal.org)" />, mentioned on his HN handle.

His blog also running D7 with 2 posts on Drupal, nothing on scale that I noticed quickly. http://johnhaller.com/development

That's it. And I run Drupal on my personal site as well as you noted. I have a handful of other Drupal sites and a couple WordPress sites I help with, too. I'll probably upgrade my personal site first and my internal test sites running on local server instances to play with.
