Thank you for your considerations. I will try contact Lars Pinds to learn from him about these additions. Meanwhile I got some advices in his personnal blog at http://www.pinds.com/blog/one-entry?entry_id=2885 where he talked about scoring users votes. It is a great lecture but i am advertised he thinks explicit votes ("rank this item from 0 to 5") is not very interesting :)
