I dont think change.org and similar sites "change" anything. And they are not directly about being political or politica sensitive. Thats for sure people should put more interest in political and social issues and again definitely people who think similar should be able to move together even in digital world but change.org fashion movements not worthy in my opinion. The main reason for my suggestion is these kind of "clicability" brings passiveness in the end. People start to think they do react politically but actually they just satisfy themselves and move on their lives. PLus change.org style websites gather pretty good amounth of information about crowds, regions, groups and individuals. So there is a big data which many organizations would be very hungry for it and we cant estimate why and how they will use that big data. The information collected obtanined by whom is a big question mark. Dramatically we give these information by our own hands in the name of taking action, being political or satisfying our conscience.
