"the rich and poor social networks did not overlap"

"Even though the people facing digital inequalities in the marginalized areas came late to the protest, Facebook still provided a platform so the residents of Gurigica, São Benedito and Itararé could organize and manifest their demands in the street protest. But the social divide that takes place in Vitória affected the way information flowed, impacting the civic engagement of the poor. The organizers of the first protests belonged to an upper class that did not overlap with lower classes, online and offline, the marginalized came in late to the streets and their voices and requests were not privileged as the ones shouted by the rich."

This is an interesting study in how class divide prevents larger protests.  Something for organizers to think about in the future.
