Abstract:

An ongoing tension within Wikipedia is characterized as the inclusionists versus the exclusionists. The inclusionists argue that one of Wikipedia's core values is that it should be open to all ideas, that truth emerges from a variety of directions. Better to include than exclude. The exclusionists see Wikipedia's utilitarianism diminished if too much froth clouds the valuable information inside. These people delete material they consider inappropriate. The case offers students a chance to understand issues such as how online cultures are made and maintained, the power of self-policing organizations, the question of whether the service is drifting from its core principles, and whether a Wikipedia-like concept can work in a business setting.
