Here is my first pass thoughts on why Buzz has opened the debate around Privacy.   It is not that Buzz is any different from the status box on Facebook and twitter, or even the one that Linked-in has added.  I think the real debate is about around the social behavior around privacy and the tools we use to manage our conversations.  Twitter exists on its own with the tools surrounding it as a certain usage case for many-to-many public discussions.  I would not think that I would want to include these types of communications in the inbox of my email, but Twitter has in fact done so with SMS and Text messaging that has been private.

I am still trying to figure out in my mind the ethos of social behavior and the tools we use, but email and twitter seem to be on completely opposite sides of my social communication graph.
