The revolution that ousted President Hosni Mubarak from power back in 2011 was partly driven by activists on social media.

As nationwide protests continue to urge the military-backed interim government to step down following a coup that resulted in the arrest of former President Mohamed Morsi, a heavy crackdown on dissent appears to have intimidated many activists who were previously outspoken.

However, the new activist group "Third square", which calls for democracy, has about 20,000 of followers on Facebook and appears to be gaining momentum in Egypt.
