Is someone trying to game this Medium story for some reason? If so, why does HN keep allowing it to appear over and over?
(14 times at last count, with tweaky URL settings to deliberately bypass HN's dupe posting filter.)
In this case the story is interesting enough to submit and gain a few points, but not enough to get to the front page, so it's not easy to link to the previous main discussion and try to keep all the comments there.
A similar problem has the "Banned by Tesla (I)" and "Banned by Tesla (II)" stories. I think one of them was more lucky, but I'm not paying too much attention because I think it's a pointless discussion.
I remember a few previous case, were one submission was very successful (front page and many points+comments) and it was unintentionally resubmitted many many many times: "The resolution of the Bitcoin experiment", "The Sad State of Web Development", "Paul Graham Is Still Asking to Be Eaten"
