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.
