I think what Jimmy just wrote amounts to a new policy -- or a fresh reformulation of something I always felt was either policy or a "feature" of our wiki software.
Some wiki boards don't track who changes what, and they don't have a problem with it. They have a low edit volume and high readership rate, so any nonsense gets weeded out quickly.
But our wiki is the world's largest, and the ratio of reads to writes isn't as high as it used to be. We _need_ user tracking.
If I see one bogus edit, like "Hi I am Johnny and I love that cutie Mary from English class" replacing the [[William Shakespeare]] article, I want to be able to click on the "User Contributions" link and see what other damage this graffiti artist has done. I'll revert everything and list the IP or username on a page where sysops and other interested parties can see it.
Also, if someone has really bad spelling or grammar skills, or goes on a POV rampage or even (*happy sigh*) writes brilliant prose, I want to be able to see more of their work.
Being able to know who does what is important around here, and maybe we should make that clear in the policy pages.
