Soon many people will be logging all their messages, either text, phone, email, or gestures and using them to recall and share with others. It won't seem strange at all. Strange will be those who opt out of life-logging -- at great expense and effort.
Life-logging may become the default, but I still think it will be the unusual person who takes the next step from logging to summarizing or analyzing their data. To many people, self-tracking simply is not very interesting.
