I'm a new Google+ account user. My account displays 15 followers yet when I go to 'People' it only reflects 14 profiles. How can I find out (SEE) who the 15th profile belongs to?
There are two options.
Either someone unfollowed you and the count on your profile is stale and hasn't been updated yet.
Or the other account has changed their privacy settings so the people in their circles are private. This conversely also covers the other direction of seeing them as followers of a profile.
