There is a concern related to social movements based on social media that a kind of ‘keyboard activism’ may replace real actions that require more extensive and intensive commitment (Van Laer and Van Aelst, 2010). Wright (2004) is concerned that CMC may establish superficial relationships, and thereby keep people’s involvement in social movements at a low level. Currently, social media users share information voluntarily through certain actions – for example clicking, posting or voting – but some critics point out that through social media people may join social movements without substantial commitment and thereby remain passive users rather than active members (Earl and Schussman, 2003; Van Laer and Van Aelst,2010). There is also a concern that social movements on social media only promote certain kinds of actions which require less effort, making these movements nothing more (Van Laer and Van Aelst, 2010). Although people can now more easily participate in social movements than ever before by clicking buttons, they might be less motivated to participate in higher threshold actions.
