"Here Comes Everybody" is a book by Clay Shirky that explores the impact of social media and digital communication on society. It discusses how these technologies enable people to collaborate and organize in new ways, leading to the rise of collective action and community engagement. The book examines various examples, such as Wikipedia and YouTube, to illustrate how individuals can come together to create and share content. Shirky argues that these platforms empower users, allowing them to participate in discussions and initiatives that were previously difficult to coordinate, ultimately transforming the way we interact and share information.
