Digg users are indeed obsessed with lists. I once posted an article to Digg titled "9 Inventions Edison Did Not Make" along with "Anatomy of a successful social network". Both reached the frontpage; but the former received 500 more Diggs than the latter, eventhough I must've spent 20x more time writing "Anatomy of a successful social network".
Digg users have severe ADD; they like to consume information fast, and then get out of the site. Lists let them do just that.
