When you don't like a comment on HN you just don't change the points of the comment. When you really think a comment is out of place you downvote a comment.<p>This is a great system. It keeps HN clean from flamebates an other spam.<p>Today my comment was downvoted. That's ok. I won't complain about that. Only this time I was very curious about the reason.<p>I like to be curious because I like to learn. And one of the best way's to learn is by your mistakes.<p>So wouldn't it be great when a downvoter must apply a simple explanation?
Or could this lead to discussions about the explanation instead of the subject?<p><i>edit</i> Changes 'posts' to 'comments'
I think this has been discussed some times before.
You may be downvoted because the Downvoter doesn't agree with your point or because he (or she) thinks your comment is rubbish. There is no way to tell the reason, but so far it seems to work fine anyhow.
