In a push technology environment, businesses and organizations will come to you with information, services, and product offerings based on your profile. how is a push technology environment different from mass mailings and spam? is it an invasion of your privacy to have organizations calling you on your smartphone every time you come near a store? why or why not? should you be able to "opt in" or "opt out" of these offerings? is this really any different from someone leaving a flyer at your house or on your car while it’s parked in a parking lot?
