This has been submitted previously. Seems like a ? has been added to the end of the URL which mitigates this being flagged as a duplicate. See https://news.ycombinator.com/item?id=8408291
Adding a query parameter is the accepted way if you want to resubmit a link. It also seems to be generally accepted to resubmit if the original submission discussion did not bring a fruitful discussion. Articles sometimes drop off the homepage very fast even tough they're interesting for multiple reasons, for example if they're submitted at US night time or if some other, controversial topic dominates the day. I saw the original submission and I like the new submission here.
