This is great. So now I can see which of my comments are getting voted up/down and so have feedback for my writing, but I have to vote other comments up or down based on content (and author sometimes I guess).
"Just curious... why author? Why not just content?"
Oh i was just referring to the "vote pg up anyway" trend.
If the author is someone you know (and I've made many friends from YC) there is a minor incentive to upvote a comment even if it doesn't read well because you know the person and can guess at what he was trying to say. So instead of judge(content), the subroutine becomes judge(content, person). It sort of feels like "voice tone" is added to a comment if you know the person. The "tone" and (perceived) intent with which something is said makes a huge difference
This could lead to a known troll getting a downvote and a known "good guy" getting an upvote for the same comment.
