Sort of related, but possibly interesting... I've created a Chrome extension that completely removes all of the voting functionality and point tallies from my interface (except for being able to upvote threads on the main or new posts page). Including removing the lighter-grey of downvoted posts. I noticed long ago that I was allowing myself to be behavior-shaped through comment voting, and saw how it had impacted my own conversation and even thought processes. Had to do away with that as much as I could.
