Why should we upvote or downvote a comment?
ErrantX: Speaking personally (and I know a few people have said the same in the past) I upvote comments that are constructive or that make a good argument and downvote trollish, rude or "lol" style comments.Irrespective of if I agree with their message or not.Examples. Take these to comments I made the other day:http://news.ycombinator.com/item?id=675136http://news.ycombinator.com/item?id=675230The first was rightfully downvoted because it all but amounted to a rant. In the second I made a much more reasoned point (but with basically the same conclusion as the first) and it got an upvote.In my eyes that is the HN effect working :)Although all of that said I have noticed a tendency for upvotes to snowball sometimes - and for some comments to obviously be voted on based on agreement/disagreement *(not that there is a specific rule against that of course!).
