I'm making an assumption here, but maybe the original folks who made up HN are voting less. so you might have newer people doing more voting, and they may not understand the quality of comments before upvoting.

similar to how google looks at more than just keywords in a document before it ranks it highly, maybe you can weight each vote. a vote cast by an early HN user isn't so binary, maybe in reality it counts as 2 or 3 votes while we call it "+1" there is a weight to their vote based on how long they've been on hn and their karma?
