&#62; Because Facebook know very well that people don't read things, they should but they don't, and they take advantage of this.<p>As far as I'm concerned, if you log into a website, and a modal dialog comes up, and you don't read what it says and just click "yes"... you deserve what you get.<p>I don't see anything wrong with things defaulting to public, either. Most things you do on the internet are public, or at least associated with your username. Such is life.
