I always wonder how HN does de-deduplication. Sometimes it works automatically, sometimes it doesn't. This was already submitted yesterday: https://news.ycombi

- grzm 7y agoThe earlier submission likely didn't attract enough attention for the later submission to be rolled in.
- braythwayt 7y agoI suspect this is the issue. When you submit shortly after another submission, it gets turned into an upvote. Or of the other submission makes it to the front post, it gets all the attention, and nobody will vote for a duplicate or want to discuss the matter again. What it takes for this to happen is a second submission some time after the first, when the first didn’t attract attention. This gives the article a “second chance,” and HN is actually interested in good articles getting second chances.
- DoreenMichele 7y agoI think if the URL is identical, a second submission within 8 hours serves as an upvote. (That submission was about 10 hours earlier.) Or if it got substantial traction, then the window is larger. If the URL is not identical for any reason, it has to be manually addressed.
