title: Nullable bool or bool with default value in action?
body: <p>Perhaps a small question but im curious.</p>
  
  <p>What is favored?</p>
  
  <p>In a controllers action, when passing arguments, when and how should they be used?</p>
  
  <pre><code>public ActionResult Action(bool aBool = false)
  </code></pre>
  
  <p>or</p>
  
  <pre><code>public ActionResult Action(bool? aNullableBool)
  </code></pre>
  
  <p>I tend to use defualt-value as its a bit more clear and eassier to check, but am i thinking wrong?</p>
