In my opinion this is a feature of HN discussions and one of the things I detest about reddit discussions.
Slashdot had the ultimate solution for our different tastes: you could configure a comment type (informative/funny/etc) modifier/threshold. You could say you wanted to see more funny replies and I could say I did not want to see them. It was a tiny bit complicated initially but I think the big impediment to adoption at other sites was the clunky UI. There is not a simple/unobtrusive way to display so many feedback options for each an every comment.
