Responses to news articles discussions....

I just responded to my first one and was surprised to see the plus, minus and exclamation signs at the end of it. Do we have any idea who we are rating or why? Do you reply to them often, once in awhile or when you see one that catches your eye? To be honest I didn't even know we could respond to them. Do we get credited the same as a response to one of our friends discussions?
