The vast majority of all email sent every day is spam, a variety of idiosyncratically spelled requests to provide account information, invitations to spend money on dubious products, and pleas to send cash overseas. Most of it is caught by filters before ever reaching an in-box. Where does it come from?
In making decisions, we often seek advice. Online, we check Amazon recommendations, eBay vendors’ histories, TripAdvisor ratings, and even our elected representatives’ voting records. These online reputation systems serve as filters for information overload. In this book, experts discuss the benefits and risks of such online tools.
For decades, social movements have vied for attention from the mainstream mass media—newspapers, radio, and television. Today, many argue that social media power social movements, from the Egyptian revolution to Occupy Wall Street. Yet, as Sasha Costanza-Chock reports, community organizers know that social media enhance, rather than replace, face-to-face organizing. The revolution will be tweeted, but tweets alone do not the revolution make. In Out of the Shadows, Into the Streets! Costanza-Chock traces a much broader social movement media ecology.
The New York Times declared 2012 to be “The Year of the MOOC” as millions of students enrolled in massive open online courses (known as MOOCs), millions of investment dollars flowed to the companies making them, and the media declared MOOCs to be earth-shaking game-changers in higher education. During the inevitable backlash that followed, critics highlighted MOOCs’ high dropout rate, the low chance of earning back initial investments, and the potential for any earth-shaking game change to make things worse instead of better.
Fresh from a party, a teen posts a photo on Facebook of a friend drinking a beer. A college student repurposes an article from Wikipedia for a paper. A group of players in a multiplayer online game routinely cheat new players by selling them worthless virtual accessories for high prices. In Disconnected, Carrie James examines how young people and the adults in their lives think about these sorts of online dilemmas, describing ethical blind spots and disconnects.
Adobe Flash began as a simple animation tool and grew into a multimedia platform that offered a generation of creators and innovators an astonishing range of opportunities to develop and distribute new kinds of digital content. For the better part of a decade, Flash was the de facto standard for dynamic online media, empowering amateur and professional developers to shape the future of the interactive Web. In this book, Anastasia Salter and John Murray trace the evolution of Flash into one of the engines of participatory culture.
Feature films, television shows, homemade videos, tweets, blogs, and breaking news: digital media offer an always-accessible, apparently inexhaustible supply of entertainment and information. Although choices seems endless, public attention is not. How do digital media find the audiences they need in an era of infinite choice? In The Marketplace of Attention, James Webster explains how audiences take shape in the digital age.
The Internet has reached a critical point. The world is running out of Internet addresses. There is a finite supply of approximately 4.3 billion Internet Protocol (IP) addresses--the unique binary numbers required for every exchange of information over the Internet--within the Internet’s prevailing technical architecture (IPv4). In the 1990s the Internet standards community selected a new protocol (IPv6) that would expand the number of Internet addresses exponentially--to 340 undecillion addresses.
Big Data is made up of lots of little data: numbers entered into cell phones, addresses entered into GPS devices, visits to websites, online purchases, ATM transactions, and any other activity that leaves a digital trail. Although the abuse of Big Data—surveillance, spying, hacking—has made headlines, it shouldn’t overshadow the abundant positive applications of Big Data.
Computers were first conceived as “thinking machines,” but in the twenty-first century they have become social machines, online places where people meet friends, play games, and collaborate on projects. In this book, Judith Donath argues persuasively that for social media to become truly sociable media, we must design interfaces that reflect how we understand and respond to the social world.
