joshu, you could give the greasemonkey script "HN OnePage" a try. http://userscripts.org/scripts/show/30512 It may not be quite what you are looking for, but it will let you easily view the comments/article for any given submission. There are some other good greasemonkey scripts out there as well, such as HN Splitview, that address this issue.
A split view makes one more likely to comment and upvote/flag etc because it is right there, and no effort is necessary to navigate back to the article's HN page.
