Chapter 5 is about Wikipedia how it started who it was started by and how it connects everyone to one another. Also how the website is a non-profit website and it is managed by the users and no one man or group. Wikipedia is a site that continues to grow and will probably never go away because information is updated daily by any of its users.
Chapter 7 goes into social organization using social media sites like twitter, MySpace, Facebook etc. Shirky talks about these different scenarios a big example was the use of flash mobs and how they can be used for fun and entertainment but also can be used for political protest. Because all it takes is a small group then that group spreads the word to their friends and their friends spread it to theirs and so on. Which demonstrated that the speed at which information can travel for people to organize and stand up for something or for enjoyment.
