I posted yesterday about a sockpuppet. A sockpuppet is when a blogger creates a fake blogging identity to smear his critics or detractors or to boost his own image but in the appearance. This is cowardice but in some instances their potentially legal ramifications.
John Mackey, the CEO of Whole Foods and avid blogger, apparently created his own sock puppet and would blog on Yahoo Finance! and elsewhere to talk himself up and bash the management of Wild Oats a firm his company was seeking to acquire.
