Being here in the Middle East we’ve been able to witness history unfold at a rapid pace over the past few months. From Tunisia to Egypt and now Libya, it seems impossible that news can move any faster than it already is. But now Al Jazeera has gone a step further and released a mesmerizing new tool that tracks tweets about Egypt, Yemen, Libya and Bahrain in real time. Apart from being fascinating to watch, it’s also an interesting tool to see topics and trends as they evolve in real time.

It was John Lennon who sang: You say you want a revolution/Well, you know/We all want to change the world. There’s no doubt the world has changed in the Middle East, perhaps fundamentally. People are saying there was a time before Tunisia, and now a time after Tunisia. In other words, the peaceful revolution that provoked Tunisia’s leader Zine al-Abidine Ben Ali to throw in the towel and flee to Saudi Arabia has changed everything in the region.
