No revolution happens without a cost. I can only hope they wouldn't have to pay much. Such events are usually followed by inflation, worsening of peoples' lives. Famine and civil war is also possible. So I don't see how can one be filled with joy. The Egyptians have a very difficult time ahead and we can only hope they will manage that without turning into another Somali or Sudan. Freedom (and illusional one like Europeans or Americans have) is a little thing compared to what's in store for the Egypt in the future. I just hope they won't regret the choice they've just made.
