Ray Ozzie has some interesting ideas on the notion of a web clipboard: "Clearly as the flexibility and potential of “mashing up” and recombining application components gets closer to someone who understands the user’s needs, the value to that user increases."
This concept relates to what I posted reently about content and conversation silos. Unfortunately, the notion expresses here is still that content is worth more than conversations...and to save content isn't automatic. I can't move it seamlessly from one application to another.
