If I can do this, so can you.
It works like this - you submit your article to Digg, choose a category, etc.
When the submission has been successful, switch to the front page of Digg and click "upcoming".
You have just captured yourself on the front page of Digg.
For example, here is my front page Digg story - "Chinglish Delivery" - it made it to the front page around 4pm today.
How long did my article stay there?
About 10.5 seconds.
P.S. Please Digg me for being a smartarse.
