I mostly agree. It's too bad that they had to lock down some of the policies against drive-by vandalism, but in the main they're still supposed to be editable. I used to edit them quite a bit. It's basically part of the workflow : if you learn something: document it. (at least from my descriptive perspective; others may disagree)

Turns out AAA banks and high tech industry also like this idea, so I've been lucky enough to be a consultant on process documentation there too.

Here's one document that seems to be editable logged out at least: https://en.wikipedia.org/wiki/Wikipedia:BOLD,_revert,_discus... See if you can find my edits on it!
