I try and keep my online activities separated.
LinkedIn is focused on my professional information and contacts. Facebook is totally focused on my close family contacts and twitter is mainly focused on my techie comments with some minor personal comments thrown in.
To my utter astonishment today I was updating my LinkedIn contacts and I saw, in the “People I may know” section my Cousin. Now I have Zero professional contact with her. She is a semi-retired professional writer who has probably never heard of CRM in her life. We have zero shared connections in LinkedIn and zero shared groups.
I don’t have her email address in my contacts, she doesn’t, to my knowledge have a twitter account I can think of no other mechanism other than my Facebook data is leaking into LinkedIn a scenario I am NOT happy about!
