I think you have to give the housemates a chance to settle it, nominations too early on can be done on first impressions which arent always right. Much prefer to have the first eviction after the second week gives everyone a chance to get to know people. And let's face it, people can change in two weeks you only have to look at Penny in BB2 what a transformation from a sensible teacher to a complete nut case in two weeks.
