Introduction: Recently, the tech blog Read/WriteWeb published an analytical article stating that after Google collaborated with several companies to launch OpenSocial, Google, users, and application developers all emerged as winners, but Facebook is certainly not a loser.
Last week, Google partnered with several other companies to launch the open social platform OpenSocial, which drew significant industry attention. Some industry insiders believe that with the support of major social networking sites such as MySpace, Hi5, Ning, LinkedIn, SalesForce, and Friendster, OpenSocial could deliver a heavy blow to Facebook, or Facebook might be forced to join the ranks of OpenSocial supporters. However, Facebook has absolutely no reason to be concerned about this.
For any social network, the "killer app" is its users, not the developer API. Most people join social networks because their friends are already there or because the site's content enhances their experience. In short, users are the primary driving force behind the growth of social networks.
