Downvoting comments because of disagreement is common in this thread. If you think about it, it is consistent with blackballing. I, for one, will upvote any well written comment I find at zero or negative values here. I don't care if I agree with the comments or not, I don't like this face of HN. I vote comment quality, not content.
