Unlike a wiki, the information will be much more granular with lots more metadata and organization. Unlike a web forum, the information will be be organized rather than dispersed throughout thousands of random posts, with little room for dominant personalities to take over. While I like Stack Overflow, I am planning far more structure. While I enjoy the entertaining tangents on Slashdot, I don't want those to take over sites created using my engine. Naturally, there must be some way to prevent armies of bots or just legions of jerks from derailing web sites created using this engine. Given that, what would you say are some good rules to include in the reputation engine for such a site. What kinds of algorithms have you found to be most beneficial to the propagation and spread of actual knowledge. What would you like to see and what have you found to be dismal failures?
