The Marmite Index is a weekly UK-based opinion poll about life, which is categorised by the people, places and things we love and hate. It is a social graph created and maintained by the opinionated fans of the Marmite Index Facebook page, the results of which are published every Friday afternoon in a humorous email newsletter. 

Initially on roll out, all of the material for the newsletter will come from the activity on the Facebook platform. However, the campaign application will grow over time and will operate across many platforms including mobile and twitter.
