Anonymous - Revolutionaries or Anarchists

Anonymous, you may recognise them by their infamous Guy Fawkes masks, popularised by the film V for Vendetta, which appears to have become an unofficial Icon for the global anti capitalism movement. Seeming to have a strong presence in the Occupy LSX camps as well as others across the globe, is this group spearheading a global revolution or are they just a group of anarchists with a lot of time to kill?
