Randyll writes "Today, Google announced its decisive entry into the world of social networks by introducing Google+, a social network tied around Google services. Its aim is to be different from other networks with emphasis on privacy and a different kind of social networking. Instead of connecting with your friends, Google+ aims to center connections around specific groups—colleagues, projects, or groups of friends—with the ability to use high-quality video chats and a unique and rich web-based user experience. It is currently in beta with opt-in invites." Several other readers submitted speculation about another mysterious new Google service as well.
