Does social media have a downside during revolution?

"During the heady days of revolution, social media seemed to unify Egyptians across disparate ideological trends around a limited, shared goal. That didn’t last. As time went on, social media encouraged political society to self-segregate into communities of the like-minded, intensifying connections among members of the same group while increasing the distance among different groups."

"The mobilization of fear was concentrated more in the politically activist communities than in the broader public. One of the most striking findings in the statistical analysis is the extremely low incidence of “fear basket” terms in the Couch Party cluster. Contrary to the common portrayal of Egypt as a society consumed by fear and chaos during this time, the apolitical group was not consumed by fear, or at least not talking about it on Twitter. Instead, fear basket terms seem to be most found within the activist cluster and the Islamist cluster, the most politicized of the groupings."

So people form cliques.  I see this every day on social media.  But I guess that's their point - what happens to a revolution when the cliques start forming?  Can you still maintain a revolution or is this a sign of the end?
