Why did you not ask the same question when the link was posted 5 days ago? That was the second time it was submitted by the same person in as many days. The real question is who cares? If it gets voted to the front page it is because people want to see it...
Because it had been posted over a year ago prior to being posted a week ago. And yes, you are right in pointing out that the same person submitted it twice in two days, but the first time it appears that nobody saw it. IMO, this is within the HN repost guidelines, but that's a matter of interpretation.
But I agree with you that "If it gets voted to the front page it is because people want to see it..."
