According to the Pew Research Center, a majority of Americans at least occasionally receive news from social media.  Because of algorithms on social media which filter and display news content which are likely to match their users’ political preferences, a potential impact of receiving news from social media includes an increase in political polarization due to selective exposure.  Political polarization refers to when an individual's stance on a topic is more likely to be strictly defined by their identification with a specific political party or ideology than on other factors. Selective exposure occurs when an individual favors information which supports their beliefs and avoids information which conflicts with their beliefs. A study by Hayat and Samuel-Azran conducted during the 2016 U.S. presidential election observed an “echo chamber” effect of selective exposure among 27,811 Twitter users following the content of cable news shows.  The Twitter users observed in the study were found to have little interaction with users and content whose beliefs were different from their own, possibly heightening polarization effects. 
Thanks Paula for commenting. I sometimes feel the same about Facebook, although I still think that it’s a great tool to have, especially in my area of work ( affiliate marketing ). I get your point that there is no real alternative to Facebook, but what the other networks don’t want to do is become a Facebook. They want to offer something different which is how they can make in-roads on the Facebook monster.
On April 10, 2018, in a hearing held in response to revelations of data harvesting by Cambridge Analytica, Mark Zuckerberg, the Facebook chief executive, faced questions from senators on a variety of issues, from privacy to the company’s business model and the company's mishandling of data. This was Mr. Zuckerberg’s first appearance before Congress, prompted by the revelation that Cambridge Analytica, a political consulting firm linked to the Trump campaign, harvested the data of an estimated 87 million Facebook users to psychologically profile voters during the 2016 election. Zuckerburg was pressed to account for how third-party partners could take data without users’ knowledge. Lawmakers grilled the 33-year-old executive on the proliferation of so-called fake news on Facebook, Russian interference during the 2016 presidential election and censorship of conservative media.
For brands, it’s a good way to objectively measure how much influence an influencer actually has, and for influencers it’s great to earn an income from the brands and products you generally love, support and naturally endorse. Affiliate marketing generally won’t be an influencer’s only source to income, as it is not reliable or steady, however, it is a good way to earn incremental revenue.

You can also engage in retail arbitrage, finding items at retail outlets for incredibly low prices and selling them for a profit on Facebook. Leverage your timeline, Facebook groups, and Marketplace as above.
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.
Digital products give influencers the opportunity to create something tangible that they can distribute and sell to their network to earn an income from their knowledge, influence and expertise. Fitness queen Kayla Itsines is a great example of an influencer empire built on digital products and influence, with her downloadable workout program Bikini Body Guide and her newly launched app Sweat With Kayla.
Usenet, which arrived in 1979, was beat by a precursor of the electronic bulletin board system (BBS) known as Community Memory in 1973. True electronic bulletin board systems arrived with the Computer Bulletin Board System in Chicago, which first came online on 16 February 1978. Before long, most major cities had more than one BBS running on TRS-80, Apple II, Atari, IBM PC, Commodore 64, Sinclair, and similar personal computers. The IBM PC was introduced in 1981, and subsequent models of both Mac computers and PCs were used throughout the 1980s. Multiple modems, followed by specialized telecommunication hardware, allowed many users to be online simultaneously. Compuserve, Prodigy and AOL were three of the largest BBS companies and were the first to migrate to the Internet in the 1990s. Between the mid-1980s and the mid-1990s, BBSes numbered in the tens of thousands in North America alone. Message forums (a specific structure of social media) arose with the BBS phenomenon throughout the 1980s and early 1990s. When the Internet proliferated in the mid-1990s, message forums migrated online, becoming Internet forums, primarily due to cheaper per-person access as well as the ability to handle far more people simultaneously than telco modem banks.
