Founded on December 14, 2002, and launched 0n May 5, 2003, LinkedIn is hands-down the most popular social media site for professional networking. The website is available in 24 languages and has over 400 million registered users. LinkedIn is great for people looking to connect with people in similar industries, networking with local professionals and displaying business related information and statistics.
Courts do not always admit social media evidence, in part because screenshots can be faked or tampered with. Judges are taking emojis into account to assess statements made on social media; in one Michigan case where a person alleged that another person had defamed them in an online comment, the judge disagreed, noting that there was an emoji after the comment which indicated that it was a joke. In a 2014 case in Ontario against a police officer regarding alleged assault of a protester during the G20 summit, the court rejected the Crown's application to use a digital photo of the protest that was anonymously posted online, because there was no metadata proving when the photo was taken and it could have been digitally altered.
StumbleUpon is a discovery engine that finds and recommends content for its users. Come June 30, 2018, it will be moving to Mix. More than 25 million people use StumbleUpon for entertainment and information. In addition, more than 80,000 publishers, brands, and other marketers have used StumbleUpon’s Paid Discovery platform to promote their businesses. StumbleUpon was owned by eBay from May 2007 to April 2009, when Garrett Camp, Geoff Smith and several investors bought it back. It is now an independent, investor-backed startup once again.
Pinterest is a perfect platform for selling products. As a virtual pin-board, the social media service is commonly used by potential customers to “pin” items of interest that they might buy later. If you created a product or are in charge of marketing one, throw some photos of it on Pinterest to shine a spotlight on it. Look at great examples of companies that utilize Pinterest to its fullest potential like TODAY, Whole Foods Market and the Travel Channel here. If you can land a freelance job doing something similar you can hit it pretty big, but you probably need the right experience to be in the running. However, small businesses also want to promote on Pinterest, and they’re more likely to hire based on enthusiasm and a go-getter attitude, so maybe start making some cold calls and emails.
Research has also shown that social media use may not have an effect on polarization at all . A U.S. national survey of 1,032 participants conducted by Lee et. al found that participants who used social media were more likely to be exposed to a diverse number of people and amount of opinion than those who did not, although using social media was not correlated with a change in political polarization for these participants .
Though research has shown evidence that social media plays a role in increasing political polarization, it has also shown evidence that social media use leads to a persuasion of political beliefs.  An online survey consisting of 1,024 U.S. participants was conducted by Diehl, Weeks, and Gil de Zuñiga, which found that individuals who use social media were more likely to have their political beliefs persuaded than those who did not.  In particular, those using social media as a means to receive their news were the most likely to have their political beliefs changed.  Diehl et al. found that the persuasion reported by participants was influenced by the exposure to diverse viewpoints they experienced, both in the content they saw as well as the political discussions they participated in.  Similarly, a study by Hardy and colleagues conducted with 189 students from a Midwestern state university examined the persuasive effect of watching a political comedy video on Facebook.  Hardy et. al found that after watching a Facebook video of the comedian/political commentator John Oliver performing a segment on his show, participants were likely to be persuaded to change their viewpoint on the topic they watched (either payday lending or the Ferguson protests) to one that was closer to the opinion expressed by Oliver.  Furthermore, the persuasion experienced by the participants was found to be reduced if they viewed comments by Facebook users which contradicted the arguments made by Oliver. 
There are lots of social apps now, and sweetalk is a new discovery. For a long time, I have searched and tried different apps and most of the time, left disappointed and frustrated, until one day by accident, the sweetalk comes into my world. And here I would like to share with you all my feelings and experiences about this mobile app. It is probably the best free transnational social tool with the function of instant translation, supporting online translation in 30 different languages and can make me learn the foreign language easily during the chat. My English is ok, so I would like to choose to send messages to the people whom I am interested in instead of my mother tongue for the purpose of improving my English better while talking. And there are a lot of lads and gals there from all walks of life around the globe(later the screenshot will be pasted). You don’t need to pay money for the VPN service, which is really fantastic for those who are eager to make friends from abroad and learn foreign language as well without the extra trouble. Of course, you can talk with the friends from your own country and if you cannot speak English well or those you want to send messages to fail to speak English, then here comes another feature of sweetalk, that is the instant translation of sweetalk. And it is foolproof to use. All right, all of these are written during the work, a little busy now and I would end this introduction of sweetalk with some screenshots, if you like it, maybe you can give it try.
Social CRM (customer relationship marketing) can be a very powerful business tool. For example, establishing a Facebook page allows people who like your brand and the way you conduct business to Like your page, which creates a venue for communication, marketing and networking. Through social media sites, you can follow conversations about your brand for real-time market data and feedback.
A 2014 Pew Research Center survey found that 91% of Americans "agree" or "strongly agree" that people have lost control over how personal information is collected and used by all kinds of entities. Some 80% of social media users said they were concerned about advertisers and businesses accessing the data they share on social media platforms, and 64% said the government should do more to regulate advertisers.
Managing social media isn’t a particularly lucrative profession yet, but it does serve a growing need for a lot of businesses. If you keep an eye out for job postings you might be able to nab a job promoting a company or brand on various social media services. A lot of those jobs are independent contractor positions, many of which you can work remotely. If you’ve got a lot of experience with social media beyond just being a user, though, you may be able to get hired to develop social media strategy. Telling businesses how specifically to approach their social media presence would very likely net you a nice income.
Social media becomes effective through a process called "building social authority". One of the foundation concepts in social media has become that you cannot completely control your message through social media but rather you can simply begin to participate in the "conversation" expecting that you can achieve a significant influence in that conversation.
Just remember that it is always a good practice to add a disclosure about your affiliate links to your social media audience. This builds up a trust with them. Secondly, don’t spam your social media communities with affiliate links as this puts off the people. Always have a healthy ratio of generic informational posts (which are of interest to your audience) to the promotional posts (with your affiliate links).
Next, instead of spamming links on Twitter and hoping for the best, keep in mind that the most honest and effective way of promoting affiliate products is through reviews. If you personally use a product and like it, and know that your followers serve to benefit from it, then write a long-form review on your blog, and share why you like the product. Don't be afraid to talk about what you like and don't like about it. You can even use video if that's more your style.
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. 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:
