I am selling Dugg Comments. There is just no time to update it, and I want to focus more on my personal blog. I am also willing to give Dugg Comments away to someone who wants to continue with where I left off.
I am sure that someone out there can vastly improve the site - such as utilizing the Digg API to automatically aggregate the best comments, or adding the ability for other people to suggest really good comments.
If you are interested in taking over Dugg Comments, please contact me here.
