"Developer's Wiki" - We're too lazy to actually write documentation on how to use the system, so we let the users reverse-engineer it and maintain the documentation for us. This has the additional advantage of having all documentation inaccessible whenever our server is down, which is often, because we don't care enough to write the documentation in the first place. And *another* advantage that there's no good starting point, and no way to know when the feature you're looking for *isn't* available!
