As one of the biggest preoccupations among adolescents is social media usage, researchers have begun using the term "F.A.D.," or "Facebook addiction disorder," a form of internet addiction disorder.[192] FAD is characterized by a compulsive use of the social networking site Facebook, which generally results in physical or psychological complications. The disorder, although not classified in the latest Diagnostic and Statistical Manual of Mental Disorders (DSM-5) or by the World Health Organization, has been the subject of several studies focusing on the negative effects on the psyche. One German study, published in 2017, investigated a correlation between extensive use of the social networking site and narcissism; the results were published in the journal PLoS One. According to the findings: "FAD was significantly positively related to the personality trait narcissism and to negative mental health variables (depression, anxiety, and stress symptoms)."[193]
Social media's role in helping businesses is significant. It facilitates communication with customers, enabling the melding of social interactions on e-commerce sites. Its ability to collect information helps focus marketing efforts and market research. It helps in promoting products and services, as it enables the distribution of focused, timely and exclusive sales and coupons to would-be customers. And it can assist in relationship building, such as through loyalty programs linked to social media.

They certainly overlap, which is why it gets confusing. For example, you can share media with your social network to gather likes and comments — a form of social networking. But you can also just upvote a link on Reddit, which is a social media platform, to help out the community and give your say in the matter without any intention of building relationships with other users.

Do not sell yourself cheap, you should always charge a fair rate for your effort and time. At times you may not even have to leave home, since it is possible to conduct coaching sessions over Skype. To increase your earning potential, sell your services and informational products. People who are interested in your advice may purchase courses and eBooks you create. Just be sure to provide value; you may even have to quit your day job and live your dream.
Thanks Mike for your comment. I don’t trust Facebook either. There’s been many times where I have seen ads come up on FB of subjects that I’ve been talking about offline. Its happened on more than one occasion which is a bit scary if you ask me. Although I do think FB has had its best days and will gradually fall in user numbers as new and innovative platforms come to market over the next 5 years.
Develop a unique voice and presence: Millions of people over the world have social media accounts. It's important to make yours stand out from the crowd by offering a unique voice, perspective or persona. Maybe you want to establish a comedy sketch channel on YouTube for example, or a Facebook page that promotes your custom-made jewelry. In any case, be sure to make your services different from the competition.
As social networking becomes more popular among older and younger generations, sites such as Facebook and YouTube, gradually undermine the traditionally authoritative voices of news media. For example, American citizens contest media coverage of various social and political events as they see fit, inserting their voices into the narratives about America's past and present and shaping their own collective memories.[93][94] An example of this is the public explosion of the Trayvon Martin shooting in Sanford, Florida. News media coverage of the incident was minimal until social media users made the story recognizable through their constant discussion of the case. Approximately one month after the fatal shooting of Trayvon Martin, its online coverage by everyday Americans garnered national attention from mainstream media journalists, in turn exemplifying media activism. In some ways, the spread of this tragic event through alternative news sources parallels that of Emmitt Till – whose murder by lynching in 1955 became a national story after it circulated African American and Communist newspapers.
Mobile social media refer to the use of social media on mobile devices such as smartphones and tablet computers. Mobile social media are a useful application of mobile marketing because the creation, exchange, and circulation of user-generated content can assist companies with marketing research, communication, and relationship development.[24] Mobile social media differ from others because they incorporate the current location of the user (location-sensitivity) or the time delay between sending and receiving messages (time-sensitivity). According to Andreas Kaplan, mobile social media applications can be differentiated among four types:[24]
