Twitter mobilizes and disorganizes depending on the attention a certain topic gets. I did an online campaign on challenging the political narrative about Pakistanis which is inherently biased and racist, and it garnered a lot of attention; it eventually ended up on Huffington Post and Global Voices. In that case, Twitter mobilized my effort. But then there was the case of several Pakistani Twitter users attempting to initiate a group of gender rights speakers, workers, etc., but it went on a tangent (by overly critical cynics) so badly, that it was just a sorry spectacle. I have seen an ample number of instances of successful campaigns and complete failures. It depends a lot on how focused you remain to keep that issue on point and relevant.
From my experience, I have worked on using Twitter to connect Mauritanian users with their fellow Arab activists to transfer expertise and knowledge in terms of cyber-activism. The nucleus of the Mauritanian “Twitteratis” is now the engine shaping the discussions about Mauritania and increasingly the conflict in Mali. Mauritania experts both in media and think tanks are beginning to rely on Mauritanian users to keep tabs on the country’s ongoing crisis. Simply put, Mauritanian Twitter users are in many ways replicating the traditional patterns of other MENA twitter users: collective thinking, strategizing, and communicating with the external world and their activist peers.

Twitter made it possible for people from different backgrounds to interact. It’s a more open free platform than other social networks, and from my experience the only limitation is the number of followers one can interact with in one time.
