How cyberspace changed politics

The above map is of Oakland created with our clima.me tool that tracks tweets from anywhere in the world that carry a geo-tag.  this shows about 2 hours of geo-tagged tweets over all of Oakland.  This morning the police 'clear' an area where Occupy protest was happening, can you guess where the cleared area is? 

If you said the area full of red tweets birds indicating recent tweets you would be right.  In the age of the Internet and mobile phones authorities ability to control space is being greatly reduced.
