"Talkativeness is afraid of the silence which reveals its emptiness," Kierkegaard once said. Now you know why sharing, commenting, clicking, and participating are pushed so strongly by blogs and entertainment sites. They don't want silence. No wonder blogs auto refresh with new material every thirty seconds. Of course they want to send updates to your mobile phone and include you on e-mail alerts. If the users stops for even a second, they may see what is really going on. And then the business model would fall apart."
