I don't remember the URL, but I read an article about Yahoo Answers which explained that the Yahoo team started off with 5-star ratings for answers, but quickly discovered that most ratings were either 0 or 5, and so changed to a Vote Up/Down system. According to Yahoo's experience, the extra complexity just adds an illusionary sense of precision with no additional benefit. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
