Digg.com has just registered the 500 000 user. 1/2 million users is alot but how many of those actually digg digg.com? I have just looked on the “top users” page. This top users page only shows users that have dugg a story. The user in last place is number 100986. This means that about 1/5 or 20% of registered users have actually dugg stories. Also of the 500,000 users about 40,000 of those users have actually submitted a story and of those 40,000 submitters only 8200 have submitted stories that have been promoted to the homepage.
