Anonymous has posted an interesting message to the world that they plan to take down Facebook on November 5th, 2011.
Interestingly, November 5th is also Guy Fawkes Day. "Wintour introduced Fawkes to Robert Catesby, who planned to assassinate King James I and restore a Catholic monarch to the throne. The plotters secured the lease to an undercroft beneath the House of Lords, and Fawkes was placed in charge of the gunpowder they stockpiled there. Prompted by the receipt of an anonymous letter, the authorities searched Westminster Palace during the early hours of 5 November, and found Fawkes guarding the explosives. Over the next few days, he was questioned and tortured, and eventually he broke. Immediately before his execution on 31 January, Fawkes jumped from the scaffold where he was to be hanged and broke his neck, thus avoiding the agony of the drawing and quartering that followed.
Fawkes became synonymous with the Gunpowder Plot, which has been commemorated in England since 5 November 1605. His effigy is burned on a bonfire, often accompanied by a firework display." (wikipedia)
