This is the story of a global movement that began when a single LinkedIn user (me) who was missing face to face connection started a local meetup, and the global movement that followed. #LinkedInLocal began as a single meeting over a coffee for fifteen strangers in 2017, and grew to over 650 cities, in over 90 countries in less than two years. This book details how the volunteer movement began, how it grew, and the lessons and reflections from the movement. The impact on careers and building a sense of belonging was profound, and demonstrates how a group of thoughtful human beings can unite communities and use social media for good. It shares many human stories of authentic connection, career change, and social impact at a local and global level. How a Hashtag Changed the World lifts the curtain on a global movement and reveals stirring stories of a community that had an incalculable impact.
