A system commonly seen on websites that allows users to express their appreciation (or lack there of) of content. Default settings can be associated with ratings, such as collapsing comments that are voted down in a threaded view. In more complex systems various ratings can be accumulated as karma that allows a user to do more or less on a site, such as the reputation used here on stack. One of the earliest rating systems on the web is IMDB's movie rating, which did not rate the content of it's users but the movie.
