Google released details of its Google+ project, a far-reaching social networking initiative that comprises a number of individual projects and services, including Circles, Sparks, and Hangouts. According to the search company, the project is designed to add nuance and depth to online interaction by adding more options and individual control to the process.
Circles allows users to cluster contacts based on relationships, allowing them to interact differently with different groups of people, rather than sharing the same interactions with everyone they're connected to-grouping contacts, for instance, into friends, coworkers, and family members. Meanwhile, Sparks lets users share content based on specific interests. Hangouts lets users interact through casual multi-person video meetings, allowing users to connect and disconnect from the group chat at will. The services also provide mobile support.
The Google+ project is currently invitation only and is still in beta.
