Wikipedia is a Massively Multiplayer Online Editing Game played by experts in redundancy, skepticism, pseudoscience, hyperlinking, reverting articles, demanding reliable sources, redundancy, verification, redundancy, identifying original research (which is often quickly denounced in the article talk pages), and initiating subtle flamewars over what is encyclopaedic.
And further down, within a list of reasons Wikipedia can't be trusted:
Most Wikipedia articles are written by people whose lives closely resemble that of that 40 year old, over-weight Comic Book virgin on The Simpsons. Therefore, they have little or no real world experience to write about.
Classic.
