They do that on ArsTechnica. It doesn't really seem to have mitigated the issue much. What I do, if I see a greyish comment on HN, and it's obvious that the opinion/idea expressed is being downvoted by groupthink, I upvote it. Even if I don't agree with the comment. Mostly because I don't believe ignoring/burying those whom you disagree with as solving anything. My choice of doing this is more of a means than an end. It's odd how narrow-minded and self-reinforcing a group of out-of-the-box free thinkers can be, especially out here. I can't impose open-mindedness on the masses, but I can try to at least help the voices of the dissenters remain visible.
