When you add a cloud service to People, you
get real-time notifications when your contacts post new photos,
comments, and tweets. Each cloud service is configuarable as part of a
“contract” that determines what information you share and who can
connect to you. When you unfriend someone or delete a contact in a cloud
service, People is smart enough to pick up on that.
