Already cited here a few times- some of the Egyptians centrally involved in organising the revolution  say so:

They are the young professionals, mostly doctors and lawyers, who touched off and then guided the revolt shaking Egypt, members of the Facebook generation who have remained mostly faceless -- very deliberately so, given the threat of arrest or abduction by the secret police.

Now, however, as the Egyptian government has sought to splinter their movement by claiming that officials were negotiating with some of its leaders, they have stepped forward publicly for the first time to describe their hidden role.

There were only about 15 of them, including Wael Ghonim, a Google executive who was detained for 12 days but emerged this week as the movement's most potent spokesman.

Yet they brought a sophistication and professionalism to their cause -- exploiting the anonymity of the Internet to elude the secret police, planting false rumors to fool police spies, staging "field tests" in Cairo slums before laying out their battle plans, then planning a weekly protest schedule to save their firepower -- that helps explain the surprising resilience of the uprising they began.

...
Mr. Elaimy, who was imprisoned four times and suffered multiple broken limbs from torture for his political work, now works as an assistant to Mohamed ElBaradei, who won a Nobel Peace Prize for his work with the International Atomic Energy Agency. In turn, his group built ties to other young organizers like Ms. Moore.

The seeds of the revolt were planted around the time of the uprising in Tunisia, when Walid Rachid, 27, a liaison from an online group called the April 6 Movement, sent a note to the anonymous administrator of an anti-torture Facebook page asking for "marketing help" with a day of protest on Jan. 25, Mr. Rachid recalled. He wondered why the administrator would communicate only by Google instant message. In fact, it was someone he already knew: Mr. Ghonim, the Google executive.
