This document provides an overview of an upcoming class titled "Friends Tweets & Change" that will focus on grassroots movements and how tools like social media, guerrilla marketing, and personal branding can help achieve movement goals. The class will be taught by Andrew Hoffman and will involve students learning about various communication tools, choosing a cause to support, maintaining social media profiles to promote their cause, and participating in discussions. The goals of the class are for students to gain knowledge of grassroots techniques, understand the power of social media, be able to teach others, and be better qualified than peers for the future. Participation and papers will determine grades.
