Comparisons of different countries and their revolutions.
Our goal is to identify trends.
Tunisia peaks first.
Egypt peaks twice - once for the massive protests and a second time when Mubarak resigns.
Bahrain peaks next, when protesters occupy Pearl Square for several days and then the police crack down on them.
Libya is currently surging. Oops that was two days ago. Now there is a peak/small decline. The country is in a revolution, but maybe a sustained level of revolutionary activity will lead to a decline in searches as some people have already done them.
Yemen - has not received much attention, despite its repeated large protests.
