5 Stars should be given to 4.5 Books.

People tend to visualize the rating system of stars to be from 0-5, but in reality on good reads our only options are 1,2,3,4,5, so if you're going to allow .5's then that also includes a solution for a 0.5 rating. Now there is no 0 star option so you'll have to give it a 1 star. So that should continue all the way up, give a 1.5 star book a 2, and so on, 4.5 books should be given 5 stars, the more people we get to understand this the more accurate the rating system will be, people rating a 4.5 star book 4 stars brings down the averages and weighs things lower. Just something to think about.
