LambdaMOO is an online community of the variety called a MOO. It is the oldest MOO today.
LambdaMOO was founded in 1990 by Pavel Curtis at Xerox PARC. Now hosted in the state of Washington, it is operated and administered entirely on a volunteer basis. Guests are allowed, and membership is free to anyone with an e-mail address.
LambdaMOO gained some notoriety when Julian Dibbell wrote a book called My Tiny Life describing his experiences there. Over its history, LambdaMOO has been highly influential in the examination of virtual-world social issues.
