Most of what I'm going to list involves sharing sponsored links, although you'll find a few other oddball things in there, too. But sharing sponsored links is where it's at because big brands want to get themselves out there to as many people as possible, and they know people are on social media all.day.long. So yes, they are willing to pay you to help them get their brand/product/message across.
Recently Facebook has lost the trust of millions of its users by allowing 3rd parties to access over 87 million users’ personal data. This is a massive breech of trust and has created a feeling of unrest amongst the social media platform’s audience. So much so that there is now a #deletefacebook campaign where people are completely removing themselves from Facebook and using other networks instead. If you’re concerned about what Facebook is doing with your data, then why not check out my guide on alternatives to Facebook, and see if there’s a better place for you to interact with family and friends.
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.
Social media personalities have been employed by marketers to promote products online. Research shows that digital endorsements seem to be successfully targeting social media users, especially younger consumers who have grown up in the digital age. Celebrities with large social media followings, such as Kylie Jenner, regularly endorse products to their followers on their social media pages. In 2013, the United Kingdom Advertising Standards Authority (ASA) began to advise celebrities and sports stars to make it clear if they had been paid to tweet about a product or service by using the hashtag #spon or #ad within tweets containing endorsements.
Bo Han, a social media researcher at Texas A&M University-Commerce, finds that users are likely to experience the "social media burnout" issue. Ambivalence, emotional exhaustion, and depersonalization are usually the main symptoms if a user experiences social media burnout. Ambivalence refers to a user's confusion about the benefits she can get from using a social media site. Emotional exhaustion refers to the stress a user has when using a social media site. Depersonalization refers to the emotional detachment from a social media site a user experiences. The three burnout factors can all negatively influence the user's social media continuance. This study provides an instrument to measure the burnout a user can experience, when her social media "friends" are generating an overwhelming amount of useless information (e.g., "what I had for dinner", "where I am now").
You might be interested to know that YouKu, Weibo, and RenRen are Chinese versions of YouTube, Twitter and Facebook. Brands who wish to reach the Asian market should be aware that YouTube, Twitter and Facebook are blocked in China. This is why MavSocial provides reach for that audience through YouKu, Weibo, and RenRen – but only in their Enterprise version.
Some online behaviors can cause stress and anxiety, due to the permanence of online posts, the fear of being hacked, or of universities and employers exploring social media pages. Turkle also speculates that people are beginning to prefer texting to face-to-face communication, which can contribute to feelings of loneliness. Some researchers have also found that exchanges that involved direct communication and reciprocation of messages correlated with less feelings of loneliness. However, passively using social media without sending or receiving messages does not make people feel less lonely unless they were lonely to begin with.
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.

Networks formed through social media change the way groups of people interact and communicate. They "introduce substantial and pervasive changes to communication between organizations, communities, and individuals." These changes are the focus of the emerging fields of technoself studies. Social media differ from paper-based media (e.g., magazines and newspapers) and traditional electronic media such as TV broadcasting in many ways, including quality, reach, frequency, interactivity, usability, immediacy, and performance. Social media outlets operate in a dialogic transmission system (many sources to many receivers). This is in contrast to traditional media which operates under a monologic transmission model (one source to many receivers), such as a newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. Some of the most popular social media websites are Facebook (and its associated Facebook Messenger), Instagram, WhatsApp, Google+, Myspace, LinkedIn, Pinterest, Snapchat, Tumblr, Twitter, Viber, VK, WeChat, Weibo, Baidu Tieba, and Wikia. These social media websites have more than 100,000,000 registered users.
