15 M, A Year After

So today is the first anniversary of 15 M, a movement created here in Spain by people who call themselves "indignados". At first I was excited by this movement who seemed to act in pacifistic ways to acknowledge there is something wrong going on in this country. But then there were government elections and I thought something would happen in the urns, but lo and behold, the PP (right wing, conservatist group) won. WTF?? So it seems this movement had no effect in the voting and is once again gathering in Sol (Madrid) and other important Spanish cities, but what for? I don't get it...
