I just revisited this thread. In a split second this comment of mine got downmodded and the one above which just said 'why?' upmodded. I really cannot reason out why. Can someone please tell me why you would do that if at all you would.
If there is something I shouldn't have said, I would benefit by knowing that.
One of the reasons I upvote an article (apart from liking it) is to bookmark and to be able to refer to it some other time (most Ask HN posts around scaling, infra, marketing etc)
If in the future PG supports this on HN itself, I wouldn't bother to duplicate.
