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.

"Metadata such as the hashtag is an important dimension of social media communication. Despite its important role in practices such as curating, tagging, and searching content, there has been little research into how meanings are made with social metadata. This book considers how hashtags have expanded their reach from an information-locating resource to an interpersonal resource for coordinating social relationships and expressing solidarity, affinity, and affiliation. It adopts a social semiotic perspective to investigate the communicative functions of hashtags in relation to both language and images. This book is a follow up to Zappavigna's 2012 model of ambient affiliation, providing an extended analytical framework for exploring how affiliation occurs, bond by bond, in online discourse. It focuses in particular on the communing function of hashtags in metacommentary and ridicule, using recent Twitter discourse about US President Donald Trump as a case study. It is essential reading for researchers as well as undergraduates studying social media on any academic course"--
