Hunch is a newly relaunched site that aims to offer users a personalized list of recommendations based on a brief questionnaire. Users log in with their Facebook or Twitter account, then answer around 20 questions to evaluate the user's tastes. Hunch then generates recommendations for movies, restaurants, music, books, products, and much more.
Hunch uses your seemingly random answers to build a profile based on what it has learned about other people. Some of the recommendations are also based on who is in your social circle, thus the Facebook and Twitter login. Most users find the recommendations eerily accurate. Some might feel discomfort at divulging this information to Hunch, but it's really not much different than what Facebook and Google already know about you.
