Don't forget to delete.
Bye Bye Google +
By now everyone should have gotten the email from Google asking you to make sure that you delete all references to Google +. Not only do you need to do on your websites, but just to be sure, you might want to delete it from your profile.
Just click on your avatar icon and go to general settings. Scroll down till you see the Google + ID. Just delete it and that should be the end of it.
Better safe than sorry!
