If I think that a post is good because of, let's say, the importance of the news, should I "like" it because I think it was good that it was reported; or should I "dislike" it if the content of the news is bad.  Let's say--nature forbid--there is an earthquake tomorrow in Iran where a number of people die, and there's a post reporting it.  Should I "like" the post because it reported the important news, or should I "dislike" it because of the content?  Can anyone help with some guidlines?
