I really like what Hunch.com are doing with like/dislike algorithms. Did you know people who read Wired prefer red heads?? Hunch even have a free SWAG offer on for badges and stickers. neat bit of real world free love. There has to be a Foursquare or AR type location mash-up in there somehow.
What I am not liking is the Facebook recommendations of; Jeremy Clarkson and the BNP. What do they think I have been browsing?????
