From the mind of Peter Denton, previously featured in this space as part of our Innovator series, this site just launched what it's calling a recommendation engine, designed to let you know which movies you should be seeing based on what your friends and loved ones have seen and enjoyed. It's hooked in to both Facebook and Twitter, which means that if any of your friends have discussed the movie or mentioned it at all, you'll hear about it. Also, your profile will let you know which of your friends have "liked" a certain flick, just to keep you in the know. Peer pressure was never quite this helpful.
