Finding Friends Via Search Query Analysis
prostoalex writes "How many times have you met an interesting person, who happened to check out the same book in the library, or listen to the same music as you do? Researchers from University of Chicago suggest that it would be kinda cool if you could find like-minded people by analyzing the queries submitted to a Web search engine. Their PDF paper explains the research in more detail."
What about AudioScrobbler? They use the music that you listen to and compare it to the music other people listen to. They then find people with similar music tastes to you, and then you can expand your tastes by looking at what they listen to.
