The bottom line of what I am going to write below is this. As you know, most of the members at Epinions are very serious about Web of Trust and individual ratings. If somebody jumps out from your Web of Trust list, you get anxious, and sometimes behave irrationally. Frankly speaking, this is not psychologically healthy. What I believe healthy is that we publish whatever we are proud of, and don't care about outliers.
Some people rate very poorly rate because of some marketing reasons.
It is granted. You can't tell others not to market their opinions. The other day, I realized that I myself was so obsessed with Web of Trust and individual ratings. I really wanted my articles to be top rated. In other words, I wanted to pull up the ratings of my articles so that I can expect more Base Eroyalties and Income Share.
