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.

It's certainly more enlightening than arguing about cryonics or libertarianism or feminism or education for the billionth time.

Any forum has reposts, it's just that some of them are literally resubmitting the same article and others are rehashing the same stupid arguments that the Internet has hosted since time immemorial.

I am a newbie here who is following HN for the past 12 months or so. Since I hadn't seen this article in those months and after having read this article I was compelled strongly to submit to HN. I thought someone who is a newcomer here should also know this and that is the only reason for me to post this.

one reason, i think, is that you can't downvote articles.
