Well, you can use the exclude() method. In a ManyToMany, the "user"
field is like a User with the additional properties defined in the
"through" model, so I think you can just do:

Question.objects.exclude(user__id=my_user__id)

Just see the examples the documentation provides:
http://www.djangoproject.com/documentation/models/many_to_many/
