After years of reading HN it's still fascinating how submissions reach the front page. I gave this the first upvote while it was still on the first page of 'new'. And i was certain that once it would go to the second page it would not get more upvotes in the weekend. To my surprise it is now on no. 1. A few crucial votes in a short time can make the difference. And i am certain that the person who submits it also plays a role. At least for me it was a reason to open the link because i recognized the name of the submitter.
