Very unlike HN to upvote a comment that has reacted only to the headline on HN, not even the articles own headline, even less the body of the article. Maybe because everyone reading the comments is doing it the same way?
How is that "unlike HN?" I pretty regularly see comments that either make it clear the author didn't read the article (e.g. arguing against points not made, or "adding" additional information that's in the second paragraph) or explicitly say they're only responding to title or some tangential point.
It's a editorialized headline that only appears on HN. The submission itself (it's content) doesn't actually say anything like the title is (was? Seems title changed)
