According to Darren from Problogger, a great secret to getting front page of Digg is to add a picture of failure itself. What I mean is to add a picture to your post showing a person in some form of grief. Anyone sad or frustrated is fine. These types of Digg posts get on the front page of Digg. If you notice Diggs front page links, you will notice that most if not all have some sort of picture along them while the least popular posts have no pictures at all. The pictures are an easy way to attract attention. Darren from problogger used this technique to attract probably millions in visitors. Although I would add that it probably helps to have a decent amount of followers to begin with. A long list of followers with the same interests is bound to get you some extra digg votes to the pint where your link will be noticed by many. Hope this technique helps!
