For Malcolm Gladwell, the role of social media, such as Twitter and Facebook, in revolutions and protests is overstated. On one hand, social media make it easier for individuals, and in this case activists, to express themselves. On the other hand, it is harder for that expression to have an impact. Gladwell distinguishes between social media activism and high risk activism, which brings real changes. Activism and especially high-risk activism involves strong-tie relationships, hierarchies, coordination, motivation, exposing oneself to high risks, making sacrifices. Gladwell discusses that social media are built around weak ties and he argues that "social networks are effective at increasing participation — by lessening the level of motivation that participation requires". According to him "Facebook activism succeeds not by motivating people to make a real sacrifice, but by motivating them to do the things that people do when they are not motivated enough to make a real sacrifice".
Users typically access social media services via web-based technologies on desktops and laptops, or download services that offer social media functionality to their mobile devices (e.g., smartphones and tablets). As users engage with these electronic services, they create highly interactive platforms through which individuals, communities, and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online.
