The primary purpose of MidnightWiki is to serve as an open repository of indiscriminant intellectualism. To that end, it has become a sort of crazy and opinionated Wikipedia slash blog slash community Bulletin Board.
Basically, the goal is to create an archive of all the great ideas that people have. The organizational structure is encyclopedic (based on categorized articles) so that these great ideas will remain accessible to everyone, for eternity. You'll find here everything from actual intellectual material that looks like the stuff found in research journals (see Sand Reckoner) to "completely useless crap."
GreatFeatures include an integrated forum and customizable skin/css of individual pages.
