This study started by focusing on the relationship between social media and social movements. Social media fosters a favourable condition for maintaining and creating connections with others, which may improve one’s social capital (Vitaket al., 2011). Social capital is derived from social relationships, which in turn provides more information and opportunities to engage in social movement activities. As shown in the Occupy Sandy example, it becomes easier to incite people to participate in social movements, ranging from promoting people’s awareness of a to getting people to perform an action in both cyberspace and physical space. People who use social media can access the information on social movements, get to know how they can participate in these movements and transmit the messages to others, which is the participatory nature of Web 2.0. With communication methods becoming more participatory, people are gaining a more developed ability to take collective actions (Shirky, 2011).
