But what worked so smoothly online proved much more difficult on the street. Police occupied the factory in Mahalla and headed off the strike. The demonstrations there turned violent: Protesters set fire to buildings, and police started shooting, killing at least two people. The solidarity protests around Egypt, meanwhile, fizzled out, in most places blocked by police. The Facebook organizers had never agreed on tactics, whether Egyptians should stay home or fill the streets in protest. People knew they wanted to do something. But no one had a clear idea of what that something was.
The botched April 6 protests, the leaders realized in their aftermath, had been an object lesson in the limits of social networking as a tool of democratic revolution. Facebook could bring together tens of thousands of sympathizers online, but it couldn’t organize them once they logged off. It was a useful communication tool to call people to — well, to what? The April 6 leaders did not know the answer to this question. So they decided to learn from others who did. In the summer of 2009, Mohamed Adel, a 20-year-old blogger and April 6 activist, went to Belgrade, Serbia.
