It depends on how much or how fast you can get diggs for your article. 50 diggs within a hour will make your article popular, but also 100 diggs for the day will do the same.
Realistically? Money, followed by interest. So a link to your proxy sites will not haul in the big boys.
Must have been a slow day for your frontpage moment, because i had between 50k and 75k on four seperate occassions within a 7 day period. (I jumped from Alexa 3,500,000 ish to 89,000ish in a week)
