I'm simply following the HN guidelines on the subject which prohibit directly asking if people have read the article.
It's a pretty bad guideline in my opinion but my opinion isn't worth shit here.
I'll re-read your comment when I have more time. Sorry if I missed the point.
Most people who bother to comment on HN have an interesting opinion, and I value yours.
The point of that guideline is to ensure that the conversation is substantive. Repeating points from the article with an assertion that those points are indeed in the article doesn't really add to the conversation and it's something that I do find frustrating on HN, which is why I mentioned it. I agree that it isn't a great guideline.
