I think the point is that this way if someone says the same thing that another poster previously did you know why. You should try to come up with the answer on your own and sometimes you will come up with the same thing as someone else. If you write down what you first think then you can get feedback about your answer. Some people decide what they'd do and then look at the posts to see if it's been said. In doing so, you will sometimes change your answer. If you grunch, you can get feedback from your initial thoughts. At least that's why I do it.
