I use the main page to view New Stories, Top, and Hot stories without needing to refresh the page. Latest Comments are nice to have on the side to see what people are discussing. Hide columns if you are not using them. I think the main feature though is the Story view, I like collapsed top-level comments and clicking on comment body to easily expand/collapse (works well on Mobile), and getting notified with link to new comment while in Story view. You can leave the page open and come back later and see new comments. I just added new feature: tab title gets updated with new comment count so you can see how many new comments while in other tabs

Login was going to add if people like the page. From what I understand there is no HN OAuth, so people would need to enter username/password which is a negative. There is a nice search feature but it is hidden, I want to integrate it better with the site. Feedback is appreciated

Agree. I really like the dense/space saving presentation. It reminds me of these stock exchange screens.
