Here's what I like about Sean Parker's approach to business in general, and social networks, in particular: he's wise to the ways of human nature. The serial entrepreneur, who helped launch both Napster and Facebook, is trying to work guilt and pride into his latest project, Agape. I'm guessing the idea is this: You're raising money to combat cocaine addiction, for example. An email goes out to your friends. They can forward the appeal. The amount each person contributes, and the money raised from those on their distribution list, is charted, publicly. The big donors get kudos, the penny-pinching are embarrassed; just like the real world. The irony: that Sean Parker — an iconoclastic thinker, and one of the few entrepreneurs who defies Silicon Valley convention by, um, having fun — should rely on peer pressure to build his next business.
