Dvorak described Twitter as "the new CB radio ". A practical use for Twitter's real-time functionality is as an effective de facto emergency communication system for breaking news.
It was neither intended nor designed for high-performance communication, but the idea that it could be used for emergency communication was not lost on the creators, who knew that the service could have wide-reaching effects early on when the company used it to communicate during earthquakes. Another practical use that is being studied is Twitter's ability to track epidemics and how they spread.
In addition, Twitter has acted as a sensor for automatic response to natural disasters such as bush fires. Twitter has been adopted as a communication and learning tool in educational and research  settings mostly in colleges and universities. Twitter has been an increasingly growing in the field of education, as an effective tool that can be used to encourage learning and idea, or knowledge sharing, in and outside the classroom.
A broad example of a hashtag used in education is "edchat", to communicate with other teachers, and people using that hashtag.

In a study, researchers found that young peoples use of Twitter helped to improve relationships with teachers, encourage interactive learning, and ultimately lead to high grades. People found that sifting through large amounts of data is challenging, however, with the simple nature of Twitter large amount of information became easily accessible. This ultimately promotes growth and learning among students and educators, not just in the class room, but virtually and around the world.

According to an analysis of accounts, the heads of state of countries and other leading politicians have Twitter accounts that have between them sent more than , tweets and have almost 52 million followers.

A study performed at Rose-Hulman Institute of Technology showed his tweets from these different time periods and through analysis of his tweets, the professors found that President Trump uses a mode called "forensic mode" the most often in his tweets.
This is described as a quick reactive usage, as they found he often used Twitter to show his judgement of the events that occurred regarding both his allies and his enemies.
After his election to the presidency he tweeted this "forensic-style" tweet, "Just had a very open and successful election. Now professional protesters, incited by the media, are protesting. In a study done at New York University in , an analysis and comparison of the Twitter accounts of Donald Trump, Jeb Bush , Bernie Sanders , and Hillary Clinton , found observations showing the goals of each candidate's Twitter during their respective primary elections.
Some comparisons that were made were the use of Aristotle's theory of Rhetoric. The research found that Donald Trump used pathos, the appeal to emotion, in his rhetoric; Bernie Sanders tended to use ethos and logos for his Twitter; Hillary Clinton tended to use logos and pathos to try to convey her values, and Jeb Bush shows that he uses a mix of all three on his account.
The study also looked at the media response to the tweets during the election. The study found that the tweets became more persuasive for the candidates if the media put the tweets in front of more viewers, versus less powerful if they were only visible to those already on Twitter. In that way, presidential candidates who had their tweets covered more in the news were able to get their message to more potential voters.

S ambassador to the United Nations , said: Twitterbots are capable of influencing public opinion about culture, products and political agendas by automatically generating mass amounts of tweets through imitating human communication. The social implications these Twitterbots potentially have on human perception are sizeable according to a study published by the ScienceDirect Journal.
Looking at the Computers as Social Actors CASA paradigm, the journal notes, "people exhibit remarkable social reactions to computers and other media, treating them as if they were real people or real places.
In addition to content-generating bots, users can purchase followers, favorites, retweets and comments on various websites that cater to expanding a user's image through accumulation of followers. With more followers, users' profiles gain more attention, thus increasing their popularity.
This practice of obtaining mass amounts of twitterbots as followers is not permitted on Twitter. Twitter is also increasingly used for making TV more interactive and social.
In December , Twitter and Nielsen entered a multi-year agreement to produce social TV ratings, which are expected to be commercially available for the fall season as the Nielsen Twitter TV Rating. In May , it launched Twitter Amplify —an advertising product for media and consumer brands.
On launch, the concept was limited to NBCUniversal channels and Xfinity cable television subscribers. In an attempt to compete with Twitter's leadership in TV, Facebook introduced a number of features in to drive conversation about TV including hashtags, verified profiles and embeddable posts.
It also opened up new data visualization APIs for TV news and other media outlets, enabling them to search for a word and see a firehose of public posts that mention it as well as show how many people mentioned a word in both public and private posts during a set time frame, with a demographic breakdown of the age, gender, and location of these people. Facebook struck the partnership to help marketers understand how people are using the social network to talk about topics such as TV.
These acquisitions, as well as a partnership with research company Kantar which it had been working with to develop a suite of analytics tools for the British TV industry since August strengthened Twitter's dominance of the "second screen" — TV viewers using tablets and smartphones to share their TV experience on social media. With the additional analytic tools, Twitter was able to improve the firm's offering to advertisers, allowing them to, for instance, only promote a tweet onto the timelines of users who were watching a certain programme.
By February , all four major U. TV networks had signed up to the Amplify program, bringing a variety of premium TV content onto the social platform in the form of in-tweet real-time video clips.
