I have a plan to summarize key principles of each section I have learned in the course textbook. Let's begin today.

Summary of key principles

Networked Individualism: People have become increasingly networked as individuals, rather than embedded in groups. In other words, people function more as connected individuals and less as embedded group members. Networked individualism is both socially liberating and socially taxing. People must devote more time and energy to practicing the art of networking and to actively network. They need to expend effort and money to electronically connect with others. Internet put more relationships easy to start, and harder to sustain because it brought so many distractions and fleeting interactions into their lives.

The triple revolution is the Social Network Revolution, the Internet Revolution, the Mobile Revolution. They shift people's social lives away from densely knit family, neighborhood, and group relationships toward more far-flung, less tight, more diverse personal networks. 
1. the Social Network Revolution has provided the opportunities--and stress-- for people to reach beyond the world of tight groups.
2.the Internet Revolution has given people communications power and information-gathering capacities that dwarf those of the past.
3.the Mobile Revolution has allowed people to access friends and information at will, wherever they go.
The changes wich the Triple Revolution brought are not all for the good or all for the bad. The effects of networked individualism often depend on personality traits and environmental contexts.

Networked individuals can have a variety of social ties to count on, but are less likely to have one permanent community. Networked individuals have partial membership in multiple networks and rely less on permanent memberships in settled groups. Individuals rely on many specialized relationships to meet their needs.

Information and Communication Technologies (ICTs) has shattered the work-home dividing line. Home and work have become more intertwined than at any time. When ICTs have shattered the line, they have also breached the line between the private and public spheres of life. New expectations and realities about the transparency, availability, and privacy of people and institutions are emerging.

Networked individuals use the internet, mobile phones, and social networks to get information, find and contact others, locate new experts to consult, get more opinions, and create new communities around themselves, their interests.
