Google Plus Update On Privacy Issues Shimrit Ben-Yair Posted In he Blog Post About Public Feedback and Make New Improvements In Privacy In comming Few Days.
"Thanks for all the great feedback everyone! We're paying special attention to privacy-related issues, which is why we're rolling a new improvement to Google+ over the next few days.
Changing your public profile picture or scrapbook photos will no longer generate a public post to the stream, just to the people you have in your circles. So only people in your circles will engage in discussions about the photos you post.
Thanks again and keep the feedback coming!'
