I think that people are rating the topics based on whether or not they agree with the topics' message. That is very interesting and valid rating criterion. In my opinion, however, I think that we should be rating them on the basis of whether the topic are interesting and whether other users should be reading the topic. What do people think. As the number of topics proliferate and there is not enough time to read all of them, people will be using the star ratings to determine whether or not it is worthwhile opening the topic and reading them.
