Twitter and social activismAlexandra Zsigmond

In The New Yorker this week, Malcolm Gladwell offers a bracing critique of the notion that social media like Twitter and Facebook are reinventing activism -- claims that were broadly made after Twitter became identified with protests in Moldova and Iran last year.

"Social networks are effective at increasing participation — by lessening the level of motivation that participation requires," he writes. And the "weak ties" created by these platforms, he adds, cannot promote the discipline and strategy that true political activism requires.

Can social media tools like Twitter nurture political action? What are their limitations and how might that change as social media mature?
