I hope this clears things up:
Wikipedia is a Massively Multiplayer Online Role-Playing Game (MMORPG) in which participants play editors of a hypothetical online encyclopedia, where they try to insert misinformation that they are randomly assigned when they create their accounts, while preventing contrary information from being entered by others. Players with similar misinformation to promote will generally form “guilds” in order to aid each other.
The source is a very rude little wiki, the Encyclopedia Dramatica.
