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.
Concerns have been raised about online "stalking" or "creeping" of people on social media, which means looking at the person's "timeline, status updates, tweets, and online bios" to find information about them and their activities. While social media creeping is common, it is considered to be poor form to admit to a new acquaintance or new date that you have looked through his or her social media posts, particularly older posts, as this will indicate that you were going through their old history. A sub-category of creeping is creeping ex-partners' social media posts after a breakup to investigate if there is a new partner or new dating; this can lead to preoccupation with the ex, rumination and negative feelings, all of which postpone recovery and increase feelings of loss.
Periscope is a live video streaming mobile app that was developed by Joe Bernstein and Kayvon Beykpour. The two started the company in February 2014 and later sold it to Twitter for $100 million in March 2015. Four months after its March 2015 relaunch, Periscope said that it had surpassed 10 million accounts and in December the same year, Apple announced Periscope as the app of the year.
You can also reach a wider audience by searching Facebook for local buy and sell groups: join these groups, follow their rules, and post what you have for sale there. Or you can go straight to Facebook's Marketplace, where they let you list an item to sell – including vehicles! You can also list homes for rent in the Marketplace, and shoppers can filter offers by location.
Many home party plans now offer consultants the opportunity to earn a living without ever holding an in-home show. Social media tools and virtual party technology like scheduling apps and graphics creation are widely available (as are the tutorials for figuring out how to use them). And almost every company today offers their reps a replicated website for selling and sharing online.
Social media often features in political struggles to control public perception and online activity. In some countries, Internet police or secret police monitor or control citizens' use of social media. For example, in 2013 some social media was banned in Turkey after the Taksim Gezi Park protests. Both Twitter and YouTube were temporarily suspended in the country by a court's decision. A new law, passed by Turkish Parliament, has granted immunity to Telecommunications Directorate (TİB) personnel. The TİB was also given the authority to block access to specific websites without the need for a court order. Yet TİB's 2014 blocking of Twitter was ruled by the constitutional court to violate free speech. More recently, in the 2014 Thai coup d'état, the public was explicitly instructed not to 'share' or 'like' dissenting views on social media or face prison. In July of that same year, in response to WikiLeaks' release of a secret suppression order made by the Victorian Supreme Court, media lawyers were quoted in the Australian media to the effect that "anyone who tweets a link to the Wikileaks report, posts it on Facebook, or shares it in any way online could also face charges".
Social media is used to fulfill perceived social needs, but not all needs can be fulfilled by social media. For example, lonely individuals are more likely to use the Internet for emotional support than those who are not lonely. Sherry Turkle explores these issues in her book Alone Together as she discusses how people confuse social media usage with authentic communication. She posits that people tend to act differently online and are less afraid to hurt each other's feelings. Additionally, studies on who interacts on the internent have shown that extraversion and openness have a positive relationship with social media, while emotional stability has a negative sloping relationship with social media. 
Information can be shared through social media at an amazingly fast pace, and users are increasingly turning to social channels to share information in real-time. This information often takes the form of opinions, so if you're listening for the right cues from your audience, social media can become an invaluable source of insights and feedback. Incorporating social listening into product development work can act as an early warning system, save on customer service costs, provide valuable development feedback, and even help identify ideal beta testers without much expense.
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.
The idea that social media are defined simply by their ability to bring people together has been seen as too broad, as this would suggest that fundamentally different technologies like the telegraph and telephone are also social media. The terminology is unclear, with some early researchers referring to social media as social networks or social networking services in the mid 2000s. A more recent paper from 2015 reviewed the prominent literature in the area and identified four common features unique to then-current social media services:
