I would agree that the comment section is not naturally below the content like most websites. However, at least for me, I'm getting annoyed with loading a full website where the comments take up 80% of the entire page. I'm assuming the point of them "hiding" the comment section is a design choice to reduce loading comments that may not be what the reader wants to read.

Maybe a happy medium would be to have a more obvious "click button" that would allow for comments.
