Here's an example of how I would use something like this: I want to watch a movie that's similar to Jurassic Park. I can go to the site and type that in. The web application picks apart the constituent pieces of "jurassic park," like "action movie" and "dinosaurs" and "made a lot of money," then looks for other movies that match the criteria based on information from IMDB, Google, and MPAA. Then, it looks for people who have voted/commented on the movie, and extrapolates a probability of you liking other movies that they have rated highly or poorly. If your rating history is similar to theirs, it rates their other movies with similar pieces higher. If your history is very different, or if they voted Jurassic Park very poorly, then the other items they voted highly are placed low on your recommendations. I think that's awesome.
