This is why I do not, and will not, use Facebook:
Facebook’s recent change in their privacy laws was held up as another example of things veering off course. What they did was to essentially create a “public by default community.” In other words, Facebook is a sign of a common occurrence throughout the social Web: we start with everything public and we have to choose what we want private. That’s the complete opposite of how the real world works, which is that you start with what’s private and you choose what you want public.
