This doesn't look like a print newspaper. Print newspapers are much denser (in general) and have different headline sizes to emphasize the editor's choice of stories. This looks like a corporate blog home page or something. Some people will like this presentation; I'm pretty happy with HN as it is. But congratulations on shipping!
Thanks for the feedback! Print newspaper's have curation, which this lacks. I guess the main thing it takes from newspapers is the image and blurb that help give you a preview of the story.
There is a form of curation on HN and "editorial judgment" on HN and that's in the points a post has. A closer approximation of a newspaper would be possible by looking at the points of a post and maybe comparing that to other posts and then sizing headlines appropriately based on how "important" the HN community sees a given story.
