Each red bird indicates a geo-tagged tweet over the past hour and its location. Tweets without geo-tags are now mapped. The more birds in a location and the darker they become. Notice that in the center of Tahrir Square there are a large number of people tweeting their geo-location, indicating a large crowd collected there.
Using our tweeter meter tool we are getting score of over 90 out of 100, which for a city like Cairo are very high. Such scores are more in line with cities like London or New York.
Following the twitter hashtag #Tahrir we can see that a lot of web data is flowing out of Cairo right now on the one year anniversary of the revolution that changed the world, inspiring people from India to Madison and perhaps leading to the Occupy movement.
