Isn't it more a matter of means vs ends. Top down is more or less means programming in which you don't really know where you are going but know how you are going to get there. Bottom up is more or less ends programming in which you don't know where you are but know how you are going to get there. Seems to me you need a good bit of both to get from where you are to where you need to be.
