I think there is probably still a little bit to be said for curation in this world. The original article was quite long (and a great read and I recommend it) and there were nuggets in it I found interesting.
I actually did try to submit the original article myself earlier today, and noticed that it had already been submitted several days ago. So at least I did upvote that.
Garry, yes curation is important, in fact, that's why HN exists, to curate and comment primary sources.
If the article has already been submitted then why try to resubmit it after copying and pasting the content into another URL?
The best way to do this on HN is to take the stance of the opposition and write an inflammatory headline, "I support (unpopular position) X, because (popular position) Y is considered harmful"
