In their most recent public statement, WikiLeaks is the only group of people to identify Anonymous correctly. Anonymous is not a group, but rather an Internet gathering.
Both Anonymous and the media that is covering it are aware of the percieved dissent between individuals in the gathering. This does not, however, mean that the command structure of Anonymous is failing for a simple reason: Anonymous has a very loose and decentralized command structure that operates on ideas rather than directives.
We do not believe that a similar movement exists in the world today and as such we have to learn by trial and error. We are now in the process of better communicating some core values to the individual atoms that comprise Anonymous - we also want to take this opportunity to communicate a message to the media, so that the average Internet citizen can get to know who we are and what we represent.
Anonymous is not a group of hackers. We are average Interent Citizens ourselves and our motivation is a collective sense of being fed up with all the minor and major injustices we witness every day.
