> I think it's a safe bet that the social networking site that replaces Facebook will have fewer features, be ugly, be more difficult to use, and have no redeeming qualities other than nobody's parents are going to participate in it, and kids will identify with it as the cool thing for that reason. Ugly or not, it will happen. Since human time is limited, a smart social strategy is all about identifying the right "circle" of people you want to join, and then performing activities that increase the chances of your interacting with people from that circle while reducing the chances of your interacting with people from outside. What this means is that even when your social site is small (compared to say Facebook), if you have all the right people in it (meaning people with high social favorability factor), you will succeed. Some people make the mistake of assuming that the larger their site is, the better off they are. It's not only about quantity, but also about quality. Low quality eventually leads to decline in quantity by driving people away. That's what happened to MySpace and what will happen to Facebook.
