A riveting, insider’s look at the creation and evolution of the like button, and what it reveals about business, technology, and innovation—and us.
quest to find out what’s behind the world’s friendliest icon. It’s a story that starts out as simply as a thumbs-up cartoon but ends up presenting surprises and new mysteries at every turn, some of them as deep as anthropological history and others as speculative as the AI-charged future.

AI critique(criticism… focusing on missing angles)
Like: The Button That Changed the World is strongest as an insider-led history of how a tiny interface feature became a business, cultural, and behavioral force. But its scope appears more explanatory and innovation-focused than a sustained critical investigation of the harms and power structures the button helped enable. manoflabook
What it seems to underexplore
-
The Facebook “Like” widget beyond Facebook. A reviewer specifically faults the book for not adequately addressing Facebook’s external-web Like button, which extended tracking and helped sharpen Facebook’s advertising and algorithmic capabilities beyond activity inside its own platform. manoflabook
-
Surveillance and data extraction. The book discusses profiling, marketing, and the value of likes as data, but it seems less focused on the political economy of surveillance: consent, opaque cross-site tracking, data brokers, and the asymmetry between users generating behavioral data and platforms monetizing it. netgalley

Mental-health effects with scientific depth. It draws on psychology and neuroscience, but a critical review could ask for more rigorous treatment of social comparison, compulsive checking, adolescent well-being, body-image pressures, and the distinction between correlation and causation in research on social media harms. The broader discussion around the button explicitly connects its feedback loops to mental-health concerns, but that issue does not appear to be the book’s central analytic project. store.hbr
-
Misinformation and political polarization. Likes give ranking systems an easy signal of attention and approval, which can reward emotional, divisive, or sensational material. The book’s business-and-innovation framing may leave insufficient room for detailed cases involving election influence, coordinated manipulation, extremist content, and the design choices that convert engagement into reach. imd
-
“Like” as a measurement problem. A like can mean “I agree,” “I saw this,” “I support you,” “this is funny,” “I am being polite,” or even “this is terrible but important.” The book likely recognizes the button’s ambiguity, but it could go farther in examining the consequences of platforms treating this context-poor gesture as a reliable preference signal. youtube
-
Who bears the costs. The book seems centered on creators, companies, platforms, and innovation. A fuller account would foreground groups with less power: children, gig workers rated by customers, marginalized communities facing coordinated harassment, journalists whose incentives shift toward engagement, and small businesses dependent on opaque algorithmic distribution. store.hbr
-
Alternatives and reforms. It apparently tells why the button succeeded, but may devote less attention to what should replace or constrain it: chronological feeds, friction before sharing, private feedback, non-public metrics, age-sensitive design, interoperability, data minimization, and regulation of targeted advertising.
A useful critical thesis
You could frame your review this way:
Reeves and Goodson convincingly explain why the Like button spread: it reduced the effort required to express recognition and generated an extraordinarily valuable data signal. Yet the book is less complete as an account of the button’s social costs, because it gives comparatively limited attention to how that signal became infrastructure for surveillance, algorithmic amplification, political manipulation, and status-driven behavior.
That critique is fair precisely because the authors present the button as having a “profound impact on modern human interaction,” not merely as a clever product innovation. store.hbr
