ETS has a new hot teams paper on Social Ratings at http://ets.tlt.psu.edu/hot-team/hot-team-social-ratings/

Social rating tools are those which allow users to rate content of items in a "repository" (e.g. a book on Amazon, a song on iTunes, a blog news post). Other users can rely on the aggregate results to determine what the overall opnion of an item. For instance, I may pick a week-end movie based on reactions from other viewers on opening weekend. For me this ties in to the aggregate decision making models discussed in The Wisdom of Crowds
