According to a 2016 article diving into the topic of sharing privately and the effect social media has on expectations of privacy, "1.18 billion people will log into their Facebook accounts, 500 million tweets will be sent, and there will be 95 million photos and videos posted on Instagram" in a day. Much of the privacy concerns individuals face stem from their own posts on a form of social network. Users have the choice to share voluntarily, and has been ingrained into society as routine and normative. Social media is a snapshot of our lives; a community we have created on the behaviors of sharing, posting, liking, and communicating. Sharing has become a phenomenon which social media and networks have uprooted and introduced to the world. The idea of privacy is redundant; once something is posted, its accessibility remains constant even if we select who is potentially able to view it. People desire privacy in some shape or form, yet also contribute to social media, which makes it difficult to maintain privacy. Mills offers options for reform which include copyright and the application of the law of confidence; more radically, a change to the concept of privacy itself.
At school, social media can be a brutal barometer of popularity. “If you meet someone new and they ask for your Instagram and you only have 80 followers,” says Sharp, “they’re going to think: ‘You’re not that popular’, but if you have 2,000 followers they’re going to be like: ‘You’re the most popular person in school.’” Sharp quit social media at 13. “I’d rather not know what other people think of me.”
Efforts to combat selective exposure in social media may also cause an increase in political polarization.  A study examining Twitter activity conducted by Bail et. al paid Democrat and Republican participants to follow Twitter handles whose content was different from their political beliefs (Republicans received liberal content and Democrats received conservative content) over a six week period.  At the end of the study, both Democrat and Republican participants were found to have increased political polarization in favor of their own parties, though only Republican participants had an increase that was statistically significant. 
The development of social media started off with simple platforms such as sixdegrees.com. Unlike instant messaging clients, such as ICQ and AOL's AIM, or chat clients like IRC, iChat or Chat Television, sixdegrees.com was the first online business that was created for real people, using their real names. The first social networks were short-lived, however, because their users lost interest. The Social Network Revolution has led to the rise of the networking sites. Research shows that the audience spends 22% of their time on social networks, thus proving how popular social media platforms have become. This increase is because of the widespread daily use of smartphones. Social media are used to document memories, learn about and explore things, advertise oneself and form friendships as well as the growth of ideas from the creation of blogs, podcasts, videos and gaming sites. Networked individuals create, edit, and manage content in collaboration with other networked individuals. This way they contribute in expanding knowledge. Wikis are examples of collaborative content creation.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, advocacy groups, political parties, and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and "trolling". Currently, about half of young adults have been cyberbullied, and of those, 20% said that they have been cyberbullied regularly. Another survey in the U.S. applied the Precaution Process Adoption Model to cyberbullying on Facebook among 7th grade students. According to this study, 69% of 7th grade students claim to have experienced cyberbullying, and they also said that it was worse than face-to-face bullying. Both the bully and the victim are negatively affected, and the intensity, duration, and frequency of bullying are the three aspects that increase the negative effects on both of them.
