Come il mondo ha cambiato i social media è il volume complessivo di comparazione dei risultati di un'ampia indagine etnografica, coordinata da Daniel Miller, dall'eloquente titolo "Why We Post". Nove ricercatori, incluso Miller, hanno trascorso 15 mesi sul campo, in diversi paesi del mondo (Italia del sud, Turchia sudorientale, due siti in Cina, area rurale e area industriale, Trinidad, Inghilterra, India del sud, Cile settentrionale e Brasile) a osservare e studiare, con un approccio etnografico, i modi in cui le persone usano i social media. È un fatto indiscutibile che i social sono entrati nella nostra vita con prepotenza, in modo capillare, per certi aspetti invasivo. Con un linguaggio fluido, talvolta anche colloquiale, il lettore è condotto all'interno di un ambito che gli sembra di conoscere, se non altro perché ne siamo tutti, più o meno, utenti, scoprendo però quanto di valori, di comportamenti culturalmente codificati, di 'polizia morale' ci sia dentro i social media. L'approccio qui presentato parte infatti da un'idea un po' diversa rispetto a quelle più diffuse, e avvalorata nel corso della ricerca: se è indubbio che i social media hanno cambiato il mondo, la questione più interessante riguarda però il modo in cui il mondo li ha cambiati.

When we click on a picture of a shopping cart it connects a complex set of technologies to represent a simple idea that we’re all familiar with. A heart icon under a photo is understood as an expression of interest or appreciation. Digital metaphors like these are everywhere in our lives, but they aren’t just a clever way to describe technology. Metaphors like “the cloud” are also changing the way we think. They are the linchpin for a constant feedback loop between us and the digital technologies we consume. Meaningful Technologies focuses on the feedback loop between digital metaphors and technology: its meaning, how it changes over time, and how it impacts learning and attention. Uniting approaches from philosophy and the cognitive and computer sciences, the authors examine digital technologies, especially social media and smartphone apps like Facebook, Snapchat, and TikTok to offer a systematic reconsideration of the ways in which digital technologies impact our lives both individually and collectively.

Substantial changes have occurred in the nature of political discourse over the past thirty years. Once, traditional media dominated the political landscape, but in recent years Facebook, Twitter, blogs and Blackberrys have emerged as important tools and platforms for political campaigns. While the Canadian party system has proved surprisingly resilient, the rhythms of political life are now very different. A never-ending 24-hour news cycle has resulted in a never-ending political campaign. The implications of this new political style and its impact on political discourse are issues vigorously debated in this new volume of How Canadians Communicate, as is the question on every politician’s mind: How can we draw a generation of digital natives into the current political dialogue?

Drawing on an expanding array of intelligent web services and applications, a growing number of people are creating, distributing and exploiting user-created content (UCC) and being part of the wider participative web. This study describes the rapid growth of UCC and its increasing role in worldwide communication, and draws out implications for policy. Questions addressed include: What is user-created content? What are its key drivers, its scope and different forms? What are the new value chains and business models? What are the extent and form of social, cultural and economic opportunities and impacts? What are the associated challenges? Is there a government role, and what form could it take?

Fabian Pfaffenberger bewertet den wissenschaftlichen Nutzen von Twitter, indem er mehrere gängige Erhebungs- und Analysemethoden betrachtet. Twitter ist mittlerweile eine beliebte Quelle für Studien, obwohl der Kurznachrichtendienst nur bedingt für die Forschung geeignet ist: Eine eingeschränkte Repräsentativität, zeitlich begrenzte Datenverfügbarkeit und geringe Datenqualität mindern den wissenschaftlichen Nutzen. Dennoch rückt Twitter aufgrund seiner gesellschaftlichen und medialen Relevanz sowie dessen Masse an frei verfügbaren Daten zunehmend in den Fokus der Wissenschaft. Der Inhalt Konventionen und Struktur der Twitter-Kommunikation Methoden der Datensammlung auf Twitter Systeme der Datenverwaltung Methoden der Datenanalyse von Tweets Eignung von Twitter als Quelle wissenschaftlicher Analysen Die Zielgruppen Dozierende und Studierende der Sozialwissenschaften, Wirtschaftswissenschaften und Geisteswissenschaften Praktiker in den Bereichen Business Intelligence, Social Media Management Der Autor Fabian Pfaffenberger (M.Sc.) ist wissenschaftlicher Mitarbeiter am Lehrstuhl für Kommunikationswissenschaft der Friedrich-Alexander-Universität Erlangen-Nürnberg.
