Are you 'Distracted', Out of Focus? Maggie Jackson raises the red flag on Multi Tasking

Maggie Jackson describes our current world as an ADD (Attention Deficit Disorder) Society in her book Distracted subtitled The Erosion of Attention and the Coming Dark Age.
She worries as The Brian Lehrer Show put it that "today’s tendency to multi-tasking has us headed for a new Dark Ages, as human beings lose their ability to pay close attention".
The last part of the title might be too much gloom and doom, nevertheless she has a point. It seems that many of us confuse getting attention and making noise.
