Order of Circles in Left-Hand Nav: Default Circles appear first in this order – Friends, Family, Following, and Acquaintances. Then your personal circles are arranged alphabetically. You can rename any of the circles, including the default ones, and renaming a default one makes it part of the normal alphabetized list. Put an underscore in front of one that you want at the top of the list. You could also delete the default circles and start over in the order that you want.(hat tip to Donna Fontenont and Joe Hall)
