from an american in Amsterdam, i've never experienced this directness thing...
Sometimes I wonder if this directness thing isn't just a myth started by the British, for whom the norm is politeness often verging on pure and simple hypocrisy.
When one cannot be polite, soft spoken, considerate, or just lacks tact, one can always go the Dutch way. Why bother?

You're going to experience the dutch directness firsthand.
Currently living in Amsterdam, and the experience is much different than what you get in/with people from the Hague, Utrecht, Bossem...
