Sometimes when reading something, you agree or disagree with what the person wrote, but sometimes you want to comment, but don't feel like going into an in depth conversation. Perhaps adding an agree or disagree (similar to facebooks "like") people who write stuff can see who agrees or disagrees with what is said. Currently the star system is all we have and that only gets used for the how much people like the topic. It would be nice to have a running count of how many people agree/disagree with each post. Just an idea.
