Articles can be resubmitted after a given time. Google shows me several submissions of this article from years ago but none recently, though citations of it do show up often in comments.

Why does it get to the front page? Because it's relevant and good, of course, unlike almost everything that is merely new.

I'm pleased to see more classics turning up on HN; Periodic reviews of the classics are the only way to get new visitors onto the same page as older ones.

One of problems with the resubmission is that it (intentionally or accidentally) ignores prior discussions until someone manually points out. The resubmission itself is not a problem, as you mentioned, however.

I guess a small link to the prior discussions or the HNSearch link to given URL will do a job. I personally prefer the latter, but it seems that HNSearch only indexes the domain name of the URL.
