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).

Uptick in US Adults Social Media Usage Will Likely Normalize Post-Pandemic

When US consumers started spending more time at home in March and April, they also started using social media more, providing an unexpected boost to the platforms.

Depending on the research source, up to 51% of US adults are using social media at higher rates during the pandemic. But even though elevated social usage continued at least into May, causing us to upgrade our forecast for time spent on social networks by US social network users, we believe that when consumers eventually get back to their normal routines of school, work and social activities, the trends will moderate. We think this will start to happen later in 2020, with a more visible downward trend evident in 2021 and beyond.

Twitters CEO thinks that social media platforms can be addictive, while Facebooks CEO does not agree with him

During a hearing before the Senate Judiciary Committee, a discussion was being held about the content moderation policies of various platforms and the impact of the recent US General Election. When Senator Lindsey Graham asked both Jack and Mark about their opinion whether their platforms can become addictive for the users, both answered differently.

As per Jack Dorsey, (like any other tech) social media platforms including Twitter and Facebook can make users addicted to continue using them. His opinion is in line with the opinions of several psychologists also who say that these social media networks give the users a sense of well-being by giving them a feeling of connection with others. One post after the other, and the urge of users to keep returning to these platforms to see newer posts one after another is like a trigger for their dopamine centers in the brain. And that is why psychologists believe that all social media platforms tend to become addicting for their users.

However, Mark Zuckerberg is of a different opinion. He stated in front of the Senate Committee that he believes that all the research regarding this matter is still inconclusive, and no one can say for sure if the social media platforms are addicting or not.

You can now create RSS feeds based on keywords with Ping.it

Imagine how useful it would be if you could set up a Google Alert for a keyword but only be notified if that word or phrase were mentioned in a news story that had more than 50 shares on social media. And would you find it even more useful if you were notified not by email but within an RSS reader?

Consider a tool that could tell you when a news story mentioning a particular word had more than 500 Facebook likes or 100 Twitter shares.

New functionality in free tool Ping.it does just that. And it lets you to determine the number of shares, Facebook likes, Twitter mentions or comments a story has before it is flagged up.

Facebook Can Not Crush These 3 Resilient Social Networks

Facebook is often considered the 800-pound gorilla of the social networking market. Its family of apps -- which includes its main app, Instagram, and WhatsApp -- grew its monthly active users 14% year over year to 3.21 billion last quarter. Facebook also shares a near-duopoly with Alphabet's Google in the digital ad market.

However, several major social networks are still growing in Facebooks shadow. Lets take a closer look at three of them, how they withstood competition from Facebook, and what that resilience means for Facebooks long-term prospects.

How Social Media Is Changing Technology

Social media and technology have evolved tremendously over the last two decades. Each one has helped the other evolve in unique ways. Technological advancements have allowed people to engage with social media on smartphones and computers. Now people are connected through social media wherever they go because everyone has a smartphone in their pocket or purse.

On the flip side, social media is changing technology as well. Computer programmers are incorporating social media networking into their software programs. There are also cases where social media influences which software programs get developed in the first place. Business technology has become largely dependent on social media in more ways than one.

Why Is a Man With No Social Media So Damn Appealing?

A man with no social presence does raise a few flags at first. What is he hiding? Who is he hiding? Specifically when it comes to dating, having no easily found information has always been a cause for concern from both parties. Those who do not subscribe to any social platforms worry about how it can affect their persona and dating prospects, while those dating someone with no social media always ask the inevitable question to friends, family or strangers on the internet: Is this person I am dating a weirdo?
