What If Twitter Was Private By Default?

Twitter is a more open network than LinkedIn, Facebook, and most other social networks out there. New users are encouraged to start tweeting with the world (potentially) listening. But what if Twitter was closed – not open – by default?

A recent bill proposed in California would require all social networks to begin with all privacy settings in place, and the user would have to manually change each one upon signing up if he or she wanted to engage in an open network.
