Hi SE Overlords and much-beloved minions!
I have always been curious why SE doesn't utilize a comment service that allows members to up and down vote comments?
I have been a loving follower of SE since damn near the onset and in the past, oh I don't know, year or so the grouchy, mean-spirited, rude comments are breaking my heart. And they are SO prevalent. You would be hard pressed to find a thread that doesn't have at least one hater.
I feel like being able see that your behavior is policed by your peers would push these people into living by the old adage, "If you don't have anything nice to say, don't say anything at all."
tl;dr - Why doesn't SE use Disqus?
