An idea: Why not implement some sort of sentiment analysis per topic? A lot of times in the "Ask HN" section it's hard to grasp whether most like the idea or hate it. Would love a quick take of TL'DR analysis of most have found this topic to be....:

?
Just a hair brain idea.
Now if they can just narrow it down to each daily topic...
