    No, 28 people upvoted it within 8 minutes without realizing that the same exact story has been in the top 10 for 2 hours. Not sure that speaks well of HN readers. I can see a few people missing it, but dozens...

      The titles are not identical, and it's not always easy to see duplicates. I don't think it's something to get down on the community about.

      Is it our responsibility to check for duplicates before upvoting a story?
      • grzm 10y ago
        The way I generally look through HN, first look through front page, then the newest page, opening new tabs as I go, I'll sometimes see and mark dupes. I think the general consensus is if you see 'em, mark 'em, but I wouldn't get overly worried about it.

            Add a comment like: Dupe: https://news.ycombinator.com/item?id=13155146 https://news.ycombinator.com/item?id=13155146 It serves as a note to others to comment on the other submission. No magic. Sometimes a mod will come by and clean up comments and mark the submission title.

      You'd be surprised (I often am) at the wide variation in the things people notice on HN. Stuff that seems obvious to you or me, many other active readers are certainly oblivious of.

  If you are asking about the algorithm, it is because the URL is not the same. The old post has some stuff at the end, while this one does not. I guess if we want the duplicate to go away, we need to flag it.
