Google's Buzz social networking Twitter-a-like has fired up a storm of privacy complaints from journalists after it has been made available for use just a couple of days ago.

Google Buzz rolled out for both desktop and mobile devices, helps keeping contacts up to date with current status.

Amidst the buzz, Google has missed one important point as it makes your Buzz friends list public by default, thereby leaking the details of the sources who wish to remain anonymous.

Google has responded to the concerns of users with a statement which seeks an explanation from the users to why a profile is required, along with a warning that "the lists of people they follow and people following them will be displayed on their profile"

Google has defended itself by stating that users can also "unfollow" people who they don't want to be linked to and can set up a public profile before they post messages. Users who click on an "edit" tab can see the choice to opt out from the default setting to make the information public.
