Verizon Business Survey Finds 68% of Small Businesses Believe They Can Recoup COVID-19 Related Losses

Verizon Business today released findings from a recent survey, Small Business Response to COVID-19 to better understand the impact small business owners and decision makers feel COVID-19 has had on their businesses. The survey, conducted by Morning Consult, focused on 500 small and medium businesses that are currently open or plan to reopen. One of the survey’s key results is that small businesses have renewed confidence, with 68% believing they can recoup COVID-19 related losses.

Key Survey Findings:

As businesses grapple with the economic impact of COVID-19, these responses highlight the assistance small businesses feel they need, the communities they feel most supported by, and the changes they have made to adjust to the new normal.

1. A Renewed Confidence
The small businesses that have weathered this pandemic to date express an overall optimism and the financial wherewithal to eventually reopen.

68% of small businesses believe they can recoup COVID-19 related losses
46% (nearly half) of small businesses that remain open say their businesses will be able to stay open for more than six months if the pandemic continues in the same way
48% of small businesses say it’s unlikely they will need to resume operations with a smaller staff
While 78% of small businesses indicate declining sales, less than a quarter (24%) say that they have missed or withheld any payments of bills (rent, utilities, etc.).

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 add a podcast by URL feed to Apples Podcasts app and other apps

When you want to subscribe to a podcast, it is usually as easy as clicking a link—often a link labeled Add to Apple Podcasts or to another popular podcast app, like Castro, Overcast, and Pocket Casts.

However, I increasingly find that a benefit of membership to editorial sites, many kinds of creators’ patronage campaigns, and subscription podcast networks includes a custom podcast feed tailored to you or only available to members. In order to prevent this feed from becoming widely distributed, it is sometimes made not quite as easy to add through a single click.

Get the Podcast URL
The plainest form of the URL, and the one that typically works reliably across all apps and services, starts with http:// or https:// and often ends with .rss. Custom feeds may instead end with a long code. For custom, paid, or membership feeds, the feed may be the only link or may be labeled as Subscribe via RSS.

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.

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.

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.

Discussion and de-escalation in social media

It is a familiar situation: a compelling discussion develops on Tw­­itter, Facebook or Instagram - it could be about any topic - but instead of working constructively towards a common solution, the tone becomes increasingly aggressive. The rift between the differing opinions grows ever larger. Often, intercultural differences and lack of understanding are the root causes of the conflict. An international research team led by the University of Göttingen now wants to develop a "moderator" using artificial intelligence (AI) that can recognise hate messages in social media and intervene to de-escalate the situation. The Volkswagen Foundation will fund the project for four years from April 2021 with a total of around 1.5 million euros.

There has been a growing change in the style of communication in social media in recent years. This is particularly noticeable when it comes to questions of cultural identity. There is increasing conflict: users become emotional and attack each other; always anxious to emphasise what divides rather than what they have in common. A constructive exchange of information, facts and arguments takes place to a very limited extent. This leads to the well-known phenomena of filter bubbles and echo chambers in social media.
