Smart Mobs & Flash Mobs
Flash mobs are usually considered to be a large group people who show up at a certain place, than so something unusual like yelling a word, and than leaving quickly. These flash mobs are coordinated also through the internet, cell phones, blackberries, PDA's, and other mobile devices. The first Flash mob was used in NYC last year but it didn't really get to do anything because the police were tipped off and were at the store before the mob could do anything. Sarah makes a great point by using what her boyfriend witnessed, about how the mob used "The Matrix" as some sort of communication.
Besides helping temporary organizations these two technologies definitely help out the "traditional organizations" by becoming much more sufficient in communicating between the people in the company as well as the different departments in the company. These two technologies help because by using more of the internet, and other mobile devices the people in the organizations can communicate even more. By using cell phones, blackberries, and PDA's those who are out of the office can still know what is going on when they are not there. This helps because if someone needs the answer to a question they don't need to wait around all day waiting for someone to show up and give them the answer. Like Danielle said it increases the Productivity. They also help within a project that is being worked on by a group of people. They are able to communicate and than go off on whatever business they have to tend to.
Smart mobs and Flash mobs are a great way for organizations to communicate and grow together without having to wait.
