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.
