I like this. Some ideas that come to my mind: Text analysis. Automatically match pages with similar content, so that even if everyone just posts their own stuff it will be connected to the rest automatically. I think the problem of a wiki-kind-of knowledge base is that pages are easily orphaned, especially if people just do brain dumps. Nobody wants to spend time tagging content, and you also don't want to manage a site-wide structure. It would be great if the content would organize itself. Could also be used to automatically link terms within text (to the most relevant page about this in the network). To extend on the "nice tricks, something that they learned about": Let students (or even professors) put their lecture notes up, structurally and visually enhanced. KhanAcademy and edX do a great job providing professionally produced courses, but maybe my friend or I can explain a specific problem better in easier terms, and you'll be even able to comment on it or provide a fix for some error.
