2 days ago I submitted a story to Digg regarding the Arizona Cardinals name of their new football stadium, and it ended up with 17 diggs. Well, yesterday while going through my RSS feed, I saw that the same story had made the digg/sports home page. One of them with 11 Diggs which is less then my submission and another with 470 Diggs and counting. Both stories were submitted well after mine, and the one currently on the sports home a whole day after.
After contacting a few of the prominent "Diggers" in the sports section (who asked to remain nameless), I asked them all the same question on how their stories always get "dugg" and I was taken aback by the answers. These "diggers" all have some sort of advanced notification system, from email list servs, message board, and even IM bots to notify their digging network.
Digg has editors; they are just ad-hoc and unpaid.
