I used Kumu to map my network, which consists of 6 main nodes:
Employer: Current employer has a closed loop between LinkedIn and Friends.
Friends: My friends are in a closed loop with Linkedin, Family, and Facebook.
Family: My family are in a closed loop with Friends, Linkedin, and Facebook.
MALAT: MALAT is in closed loop with only Friends and LinkedIn.
LinkedIn: LinkedIn loops with all nodes, except Facebook.
Facebook: You can only be on my Facebook directly from either Friends or Family.
