Nudging towards a Big Society?

While the Big Society may seem to offer the possibility of an opening up of civic involvement, will this in fact usher in a new dawn of autonomy from the state as promised?

Or is the Big Society another way of encouraging a prescribed notion of social responsibility, whether that be recycling, parenting or indeed individual health? And if the aim of the Big Society (like Nudging) is to create new social norms while not (overtly) involving the state, then what is meant by autonomy today?
