In some sense I agree, but what has bothered me lately is the fact that Googling for "wikipedia foo" likely brings up one of our mirrors first, and not Wikipedia itself. So when I see a blatant error magnified "n" times on the many mirrors on the Internet, it sends a chill up my spine.

Worse, because those sites are mirrors, and don't accept changes, it makes it easy for readers to walk off and say, "What a crackpot project."

Of course, the only way to correct that is for Wikipedia to *fix* the information, not to delete it. If Wikipedia deletes the article, it will still remain in many of the mirrors and therefore in google. If we instead keep the article but remove the fluff (advertisements, POV, original research), then the mirrors get updated and so does google.
