Image by jdlasica via FlickrOn Facebook there is symmetry, we have to friend each other. On Twitter there is asymmetry. You could argue there is asymmetry also on Google Plus. So far I have not had to ask for anyone's permission before adding them to a circle. But where Google Plus is different from Twitter is I can only add a total of 5,000 people to circles. On Twitter I follow and am followed by 45,000 people.
A million people might still add Ashton Kutcher to their circles, but Kutcher can not reciprocate. He can only add 5,000 people to his circles. And so the experience stays intimate for both Ashton Kutcher and his fans. His fans also have that 5,000 limitation. And so there is quality to that circling. Those fans can not add 50,000 people to their circles. That adds value to every time you get added to some circle.
