My internal version: Upvotes mark signal Donwnvotes mark noise That said, I do think I have a non-linear response. If I see a comment at -1 which I think has genuine signal I upvote it, even if I completely disagree with the point made. However if the same comment is at +10 I will not upvote it if I don't agree with it. I am more worried about the duplicates though, I wish there was an easier way to figure out you are submitting a duplicate story besides conducting a prior search. Something like "Thank you for your submission, here are some stories from HN with the same keywords in the last few months, are you sure you want to go ahead?" would be nice.
