Super Crunchers (2007)
“Recommendations make life a lot easier. Want to know what movie to rent? The traditional way was to ask a friend or to see whether reviewers gave it a thumbs-up.
Nowadays people are looking for Internet guidance drawn from the behavior of the masses. Some of these “preference engines” are simple lists of what’s most popular. The New York Times lists the “most emailed articles.” iTunes lists the top downloaded songs. Del.icio.us lists the most popular Internet bookmarks. These simple filters oft...en let surfers zero in on the greatest hits.

This is truly “collaborative filtering,” because your ratings of movies help Netflix make better recommendations to others and their ratings help Netflix make better recommendations to you.MoreLess
