During revolutions, things happen so fast that one can't actually have control nor even clear understanding of what is going on. Post revolutionary eras are mostly unpredictable. Pre-revolution is the best course of any revolutionary progress; it engages wide range of popular participation and is determined to a goal of laying tyranny down. That's not the same for post revolution era.
Revolutionaries don't usually talk to each other what kind of change they've to bring. Even if they do, they care less for the differences existed between them. They just work together to topple whom they call an obstacle for their esteemed change.
This working together towards different goal brings a problem when they succeed. It's true that predators agree until they will have to split their prey. After a revolution, come other successive revolutions. This is either because each revolutionary wants to take the key position to bring about their change or because the thrown ones want to come back in different colors.
Revolutions are participatory. Like the man behind the Jan 25/2011 Egypt revolution, Wael Ghonim, said it, they help in realizing “the power of the people is greater than the people in power". However, no one can surely tell not only whether the revolutionary people owns the fruit of the revolution or not; but also whether the change is for good or not. Now - 3 years after the revolution, in Egypt, Wael Ghonim's name is labeled as “foreign agent" and he is living in Dubai. If he goes back to Egypt, he will join his friends in jail. Friends of Mubarek are now back in power.
