Why should we upvote or downvote a comment?
Tichy: I see it less as agreeing or disagreeing, and more as is it a new idea, new perspective, new spin, something worth thinking about. I would not learn anything from a comment about liberal arts education being crap. If there was an interesting reasoning behind the comment, it might be another matter.Sometimes I vote up things I disagree with, because I am interested in the opinion of the HN community on the issue.
