You are on to something with this... I find the chain of socials interesting. Friendster was huge. This got eclipsed by MySpace which was huge. And then run into the ground by Fox Interactive. Like you would have to try hard to mess up as bad as they did. Tthen that got eclipsed by Facebook. It's like they either were different versions of same concept for subsequent tech deployments or they needed to position a front person that would play ball. Facebook really grew when it have the sign in for social tools on all sorts of sites.
