I have written on my personal blog about what I am starting to call "Personal Reality".
As I wrote there:
Personal Media includes your friend's shared items. It includes the comments you leave on blogs. It includes Social Media. But it also includes private updates. Updates from your Intranet. Updates from your family. Updates from broadcast media. Updates that matter to you - no one else.
Personal Media is about recognizing that people are social and private. They are interested in personal experiences.
