In Up to Date, Tong and Van Der Heide explore the spicy, unsetting--and sometimes just exhausting--universe of digital romance. As dating platforms like Bumble, Tinder, and Grindr proliferate, scholars have had to stretch their understandings of how courtship works, often arriving at fascinatingly counterintuitive theories about how twenty-first century daters shape online identities, select mates, mediate conflict, and maintain or terminate romantic relationships. This book guides readers through an increasingly complex and extensive literature, highlighting strengths and weaknesses of existing approaches, while establishing new avenues for the future. Written for both students and seasoned experts alike, the book also addresses the largely invisible underpinnings of what has become a multibillion-dollar industry, including propriety algorithms and perverse economic incentives. Up to Date is a provocative and rigorous must-read for anyone who seeks to understand or conduct research regarding the social science of online romance.
