To fix social media, we need to introduce digital socialism

Breaking up Big Social Media sounds great, but how would this look in practice? A number of legal scholars and politicians have proposed reforming social networks by using antitrust law and regulations to create a more competitive marketplace. Leaving this task to market forces, however, is a bad idea that will not solve the central problem: proprietary control of the networks and the exploitation of user attention for profit.

A solution based on digital socialism is needed to transform social media into a global democratic commons. This would eradicate Big Social Media by placing ownership and control directly into the hands of the people.

Various scholars have put forward two main ideas to break up Big Social Media, neither of which can sufficiently accomplish their goals.

The first one seeks to dismantle past mergers and acquisitions. Facebook, for example, bought up Instagram and WhatsApp years ago, and is now seeking to integrate all three platforms into a seamless communications network.

The second idea proposes a solution to this problem: make social networks interoperate. Social media platforms would be forced to allow members of one network to interact with members of another. For example, a Facebook user would be able to post a comment under a YouTube video while logged into Facebook, and vice-versa. Users data would also be portable so they could move their profile to a different platform.

Your own personal news package: The next generation of RSS feeds

It was back in 1999 that RSS feeds originated as a way of getting an overview of new articles and blog posts. They are still around today and can still be useful if you want to tailor and streamline your reading content.

RSS feeds can be used to bundle news from any number of websites within a program, browser extension or app. The only requirement is that the pages must support the.rss or.xml file extensions.

The advantage of RSS feeds and readers is that not only are they often free of charge, they also reduce your data use, as only a section of the article is loaded, Neuhetzki says.

In addition, the user does not have to provide personal information such as an email address or register in order to use a feed.

Americans Who Mainly Get Their News on Social Media Are Less Engaged, Less Knowledgeable

The rise of social media has changed the information landscape in myriad ways, including the manner in which many Americans keep up with current events. In fact, social media is now among the most common pathways where people – particularly young adults – get their political news.

A new Pew Research Center analysis of surveys conducted between October 2019 and June 2020 finds that those who rely most on social media for political news stand apart from other news consumers in a number of ways. These U.S. adults, for instance, tend to be less likely than other news consumers to closely follow major news stories, such as the coronavirus outbreak and the 2020 presidential election. And, perhaps tied to that, this group also tends to be less knowledgeable about these topics.

Through several surveys over the last nine months, the Center’s American News Pathways project has been exploring the connection between Americans news habits and what they hear and perceive about current events. One important aspect of this project is taking a deeper look at the pathways, or platforms, Americans use most often to access news – such as news websites or apps, social media, local, cable and network TV, radio, or print.

As of late last year, 18% of U.S. adults say they turn most to social media for political and election news. That is lower than the share who use news websites and apps (25%), but about on par with the percent who say their primary pathway is cable television (16%) or local television (16%), and higher than the shares who turn to three other pathways mentioned in the survey (network TV, radio and print).

How to Automate Your Social Marketing Efforts

With all the social media site tools available, often the best way to be effective with your social marketing is to automate the process. First, you need to decide whether automation is right for you and, if so, which automation you should set up. Automation can be key in turning your contacts into profits because you can post less, but at the same time, you get more exposure. Social automation, however, can be considered spamming, so be careful with how you set it up.

How does social network automation work? There are tools like Hootsuite and SocialFlow where you can automate your social networking sites or TubeMogul to automate your video posting. These sites can submit a link or post to not just one or two sites but, in some cases, up to 60.

Social media users more likely to believe false information

A new study led by researchers at McGill University finds that people who get their news from social media are more likely to have misperceptions about COVID-19. Those that consume more traditional news media have fewer misperceptions and are more likely to follow public health recommendations like social distancing.

In a study published in Misinformation Review, researchers looked at the behavioral effects of exposure to misinformation by combining social media analysis, news analysis, and survey research. They combed through millions of tweets, thousands of news articles, and the results of a nationally representative survey of Canadians to answer three questions: How prevalent is COVID-19 misinformation on social media and in traditional news media? Does it contribute to misperceptions about COVID-19? And does it affect behavior?

How can we make social media a healthier platform for health information?

Misjudging information can spiral out of control in hours. Researchers at the Harvard Kennedy School highlight that misinformation is a major threat to global public health(opens in a new tab), especially when there is a large lag between the emergence of a disease and an effective solution. Examining COVID-19, they identified that the lag time for vaccine development has created a vacuum for scepticism to grow and misinformation to spread – which has been amplified by bots and trolls.

Social media is designed to share information we believe to be correct, quickly, and works on gut-based intuitions where patterns are rapidly recognised, and biases quickly confirmed.

Misinformation is having a serious impact on our health worldwide.
