Now, years ago, when I was working at YouTube, we were looking for ways to encourage more people to rate videos, and it was interesting because when we looked into the data, we found that almost everyone was exclusively using the highest five-star rating, a handful of people were using the lowest one-star, and virtually no one was using two, three or four stars.
