If a story dugg by a power digger then it has more worth than even 50 Diggs by ordinary profiles. Bet me it is not much harder to hit Digg Front page, but it is much harder to find powerful digg on your story. I am exploring digg criteria now a days and i found that
1. Yoiur story must be digg within 2-3 hours by at lest 40 to 50 people from Different IP( must) and with people having profile at least 2 to 3 months older, their is 100% chance that your story hits Front page of Your Category in Upcoming Sections
2. When Your Story hits Upcoming Sections, you need some powerful Digg Votes from some power users having popularity ratio above 50%
3. Digg Diversification plays vital role to hit your story on Digg Front page.
Hitting Digg Front page normally required 100+ votes and 300 votes for sidebar. Here if IMT's can make a digg group then they can make their stories viral. I am sure some of them here are Power Digger Users and they can explain the whole process much better way.
