Book excerpt: This book explores how social media is used in South Africa, through a range of case studies exploring various social networking sites and applications. This volume explores how, over the past decade, social media platforms have deeply penetrated the fabric of everyday life. The author considers South Africans’ use of wearable tech and use of online health and sports tracking systems via mobile phones within the broader context of the digital data economy. The author also focuses on the dating app Tinder, to show how people negotiate and redefine intimacy through the practice of online dating via strategic performances in pursuit of love, sex and intimacy. The book concludes with the use of Facebook and Twitter for social activism (e.g. Fees Must Fall), as well as networked community building as in the case of the #imstaying movement. This book will be of interest to social media academics and students, as well as anyone interested in social media, politics and cultural life in South Africa.
