I read HN in Google Reader in a tabbed browser, and I think I would prefer a feed that reversed the order of the two links. So that the first link goes to the HN comments, and the second link goes to the article itself.

That would allow me to use Google Reader's List view which does not display the expanded, secondary link, and then go down that list of HN articles, open the intriguing HN comments in a background tab, and then when I get to the tab, click on the link in the comments that takes me to the article itself.
