Lulzsec and Anonymous Declare Open War Against All Governments and Fat Cats - Gizmodo

What does this mean?
What's going to happen due to this declaration?
What are the 'real' (physical) world repercussions that are going to be felt?

Is this the start of fed up individuals actually trying to expose corruption and get lawmakers to do good for Humanity?

Or is the U.S. gov that smart..
