Which makes me think maybe HN should have some mechanism to say "This article is related to this other one", and point to the HN submission for it. I guess our user comments here in this subthread are that mechanism. By the way, this whole thread is an implementation of the new HN algorithm that revives threads that are missed on first submission and gain upvotes later. I notice that is implemented by resetting the submission date on the submission. (I was the original submitter, so I remember when I first submitted this thread.)
