Music, movies & books are good indicators of taste and therefore you can use them as parameters in similarity search on user-user matrix. It is called nearest neighbors search or clustering in academic jargon and there are many possible solutions, mostly based on some sort of matrix decomposition. Look at this one for example, the winner of Netflix challenge: http://public.research.att.com/~volinsky/netflix/BellKorICDM07.pdf http://public.research.att.com/~volinsky/netflix/BellKorICDM...

This is interesting, since I've been thinking for a while that your Netflix queue might serve as a decent proxy in tests about whom you might click with (either romantically or just-friends). If I think of the things my friends and I have in common, of all the aspects of their lives (interests, hobbies, politics, etc) maybe the one where we have most overlap is in the types of movies we like. Maybe this is not supported statistically across the population, but I would be curious to see a study on the correlation between the similarity of two people's Netflix queues and a measure of how much those two people click as friends. The similarity of the queues is easily quantifiable, but one would have to come up with a quantifiable measure of how much two people click. If they are friends on Facebook, you could see how much they interact: the higher the interact, the higher they click (of course this may not always be the case).

Two thoughts. First: "when you don't create things, you become defined by your tastes rather than ability. your tastes only narrow & exclude people. so create." --why Second: I've had many fulfilling friendships with people who didn't enjoy the same music, movies, or books. I think that's a really crappy way to make friends, and a really good way to encourage people to isolate themselves even more into cultural echo chambers.
