As the protests are playing out in the streets of Cairo and the rest of Egypt today, I have been glued to the live-stream of Al Jazeera English as well as the Twitter hashtag #Jan25, a top trending topic based on the big protests a few days ago. The Egyptian protests come on the heels of a similar revolution in Tunisia, where a longtime dictator, Zine El Abidine Ben Ali, was ousted after young people organized protests via Facebook. We’ve heard about “Twitter revolutions” before in Iran after huge protests there in 2009, but how have things changed today? How much of a role has social media played in the turmoil happening in the Middle East? Will that continue to be the case?
