The worst part is how Wikipedia does not have a logical user introduction flow. They have an insane amount of rules and process but they will very quickly drop a brand new user in to a text box and make it look like you simply type in some stuff and the page will be created.
They need some kind of reputation system to ramp up users to greater and greater feature sets like stack overflow has rather than pretending a brand new or unauthenticated user can just create a page.
