Pretty off topic, but I submitted this story last night [1] with the exact same URL and title. I thought whenever duplicate stories were submitted, it just upvoted the original submission without posting a duplicate story (that's what's happened to me in the past).
I originally saw this, and thought the URL was just different (even if just slightly), so I wasn't even going to say anything.
But since the URLs are identical, was just curious how the HN logic works when submitting duplicate URLs like that. Is it that too much time had passed, considering them "different" submissions?
