Document Summary
Chapter 10: facebook: a billion-plus users and big business from the social graph. Short: short selling is an attempt to profit from a falling stock price. Short sellers sell shares they don"t own with an obligation of later repayment. They do so in the hope that the price of sold shares will fall. They then repay share debt with shares purchased at a lower price and pocket the difference (spread) between initial share price and repayment price. Social graph: the global mapping of users and organizations and how they are connected. Facebook has strong network effects and extremely powerful switching costs. Differences between mobile app and desktop services: Smartphone apps can access a user"s address book, making it easier to rebuild the social graph. Smartphone apps can access a phone"s media library and cloud storage, making it easier to share photos and video. Smartphone apps can use push notifications, increasing engagement.
