Gregory Ferenstein offers another cautionary tale about Wikipedia:
Wikipedia editors unearthed a clever hoax perpetrated on the web’s gullible netizens, sending the mighty "Bicholim Conflict" back to where it originated: non-existence. For five years, the imaginary year-long battle, from 1640 to 1641, between Portugal and the mighty Indian Marath Empire, reigned as truth in the user-generated halls of Wikipedia’s archive. Despite the fact that the cited sources were as real as the conflict, it even achieved "Good Article" status for its thorough 4,500 word recounting of the major historical event. It is said that history was once written by the victors; now, history is also written by the bored.
