Pretty soon, just about every site may have a social-networking component, Forrester Research analyst Charlene Li wrote in her blog. While MySpace and Facebook are extending their reach even further, Google is tapping into the social Web in its own way. Google says its new feature gives site owners the tools to "attract and engage more people by giving visitors a way to connect with friends on their websites." So sites that would otherwise not have any social-networking features can, through Google, add tools that let visitors see, invite and interact with their friends.
