Ask HN: Review my startup, GroupMo

The Pitch: GroupMo provides an easy way of organizing your facebook friends to see a movie. You can peruse movie content and see which facebook friends expressed an interest in seeing each movie. Then, you can round them up by creating a group, invite individuals, and broadcast your movie-going plans on facebook. GroupMo could help people learn about friends' tastes and discover new friends to see a movie. http://www.groupmo.com We're interested in feedback on your experience, suggested improvements, and the concept generally.
