The anatomy of the Sony Nexus X hoax →
Let me reiterate: I, an individual with no previous worldwide recognition save for a frontpage Reddit post, managed to alter the behavior of people in Russia, Japan, Uzbekistan, and Italy within the course of 24 hours, all from the comfort of my home while exerting next to no effort.

He explains the hoax and his motivations in the linked article.
Utterly entertaining story for a quiet Saturday evening.
