All the content is still plainly visible with no extra clicks or screens. In the standard interface I often miss hackernews comment rankings unless they are highly negative (causing the comment to be grey). The comments are also broadly divided by topic (the post itself) whereas a facebook feed is a firehose of 'anything that might engage the user'. These two facts alone heavily dispute your argument in my opinion.
