Egypt has decided to follow Tunisia's example and overthrow a president who has been in power for 30 years. A ridiculous thing the government did was turning the internet off and thereby such social media as Twitter and Facebook.
I cannot help myself in thinking the 20th century was vastly characterised by revolutions, global wars, regional upheavals and the worst of tyrants. Here are a few countries that experienced revolutions: Algeria, China, Cuba, Hungary, Indonesia, Iran, Mexico, Nicaragua, Russia, Spain, Turkey and Zanzibar. The number of countries that saw a change of government is even greater and includes France, Germany, Japan and most countries in Europe and Africa. And the list goes on!
As far as I know, absolutely none of these revolutions had anything to do with Twitter or Facebook!
