“If you want to liberate a society, just give them the Internet,” Ghonim said in an interview with CNN.

Ghonim gives credit to the young Egyptians who organized themselves on Facebook, dating back to last June when activist Khaled Said was killed. Ghonim commented on how a video posted on Facebook (where he is administrator of a page commemorating Said) would be quickly shared by 50,000 people, calling Facebook CEO Mark Zuckerberg a personal hero.

Ghonim said he plans to write a book on the topic called “Revolution 2.0.”
