While social media is credited for helping the Arab Spring movement, social media movements don’t always succeed. Take the “Save Darfur” campaign as an example:

Focusing on the Save Darfur cause, which took Facebook by storm between May 2007 and January 2010, the team looked at the donation and recruitment activity of over one million members. Roughly 80 percent of the members joined via a referral, whereas only 20 percent joined of their own accord.Furthermore, of the one million-plus members, 99.76 percent failed to ever actually donate any money. 72.19 percent didn’t recruit anyone else, entirely missing one of the main advantages of online activism: the ability to reach out to a very large and connected audience…

“The study is an important counter-balance to unbridled enthusiasm for the powers of social media,” said UC San Diego’s Lewis. “There’s no inherent magic. Social media can activate interpersonal ties but won’t necessarily turn ordinary citizens into hyper-activists.”…

The research was published in Sociological Science and was co-authored by Kevin Lewis, of the University of California, San Diego’s department of sociology, Kurt Gray of the department of psychology at the University of North Carolina, Chapel Hill, and Jens Meierhenrich, department of international relations, London School of Economics.

The advantage of social media for social movements is that it is easier to attract attention. Information can spread quickly and social movements can become popular things to support. The catch, however, is one that always seems to plague modern social movements: once people are informed, how exactly can they be convinced to actually act? Social media makes the bar for joining online quite low but that doesn’t translate into much physical action. Another example is the Kony 2012 campaign: lots of attention and views but limited follow-through.

Perhaps the difference between Save Darfur and the Arab Spring is that physical action was already occurring in places like Tunisia and Egypt and social media helped fan the flames. But, starting everything through social media is a tall order.
