If you currently have a private profile on Facebook and was hoping to have the same on Google+, you can… until July 31, 2011 that is. Google lays out the details on the social services help section:
“The purpose of Google Profiles is to enable you to manage your online identity. Today, nearly all Google Profiles are public. We believe that using Google Profiles to help people find and connect with you online is how the product is best used. Private profiles don’t allow this, so we have decided to require all profiles to be public.
Do you think this will have a negative effect on Google+ when in launches to the public? Tell us your thoughts.
Keep in mind that your full name and gender are the only required information that will be displayed on your profile; you’ll be able to edit or remove any other information that you don’t want to share.
If you currently have a private profile but you do not wish to make your profile public, you can delete your profile. Or, you can simply do nothing. All private profiles will be deleted after July 31, 2011.”
Essentially, if you leave your Google+ profile private, Google will simply delete it after July 31, 2011.
