Anonymous is almost certainly not what you think it is. You have to live it to understand it, its implications, its functioning, and its place in society. Gabrielle Coleman lived it, as a fully disclosed academic anthropologist. This is her story as much as theirs.
The structure of Anonymous is like the structure of the internet: multiple channels, multiple entry points, self healing patches, and lots of redundancy. (Also lots of swearing, lots of personal attacks, and lots of suspicions. Testosterone is involved.) This enables a totally flat organization to achieve in minutes what giant corporations and government take years to effect. The exhilaration, the joy, the satisfaction participants savor is incomparable. Anonymous is far more than a labor of love; it is idealists executing on their dreams. Everyone should be jealous.
