It may seem negative to you, and in a particular light I can see that perspective, but you should ask whether those comments truly provide any meaningful contribution to the discussion.<p>I have been seeing everything from "+1" or similar to "Wow that's great", and while positive, they are ultimately useless comments. They don't contribute in any meaningful way to the discussion. I will <i>always</i> downvote anything that doesn't add meaning.<p>We are worried about trolls, but all too often we forget about the happy Flickr effect. This means that if you put up a photo on Flickr, almost 99.9% of the commentary you will get on it will be positive. "That's a great photo, good job, +1, WOW, etc". When all of the feedback on your content is purely negative or purely positive, its effectively meaningless.<p>Our jobs as users of HN is to maintain the traditional high level of discourse as much as possible. That doesn't mean to be assholes or ever-loving angels, but to be in the middle. If you read through my comment history, its a combination of positive and negative. I even recognize that sometimes I forget my own advice and think I come across as too critical or too approving.
