Oberwiki is Oberlin's personal wiki. It contains sporadic and mostly outdated information about Oberlin and Oberlin culture. It seems like most of the edits and pages were made between 2005 and 2007. Take everything you read with a grain of salt.
Basically nobody has modified it in the last 4 or 5 years. By my estimates, half the information is outdated, a quarter of it is irrelevant, an eighth of it is in-jokes about people nobody remembers, and an eighth of it is good, relevant info.
See Oberwiki:About for a more formal definition.
