Not sure this is the right direction. In HN the right side of the screen is underutilized. Maybe you can have the list on topics on the left, and previews on the right, etc. Or have the right area to be customizable... But I like having a list of topics since it allows you to discard the ones that are uninteresting faster. Maybe if you could also have tags like in slashdot and filter tags that would be good too, but HN doesn't have tags.
