“ Contributors to Wikipedia have wondered aloud lately if — perish the thought — they are running out of topics. The obvious articles, low-hanging fruit like “China,” “Moses” and “Homer Simpson,” have been written and rewritten hundreds of times. … But these concerns seem misplaced — Wikipedia can no more be completed than can New York City, which O. Henry predicted would be “a great place if they ever finish it.” In fact, with its millions of visitors and hundreds of thousands of volunteers, its ever-expanding total of articles and languages spoken, Wikipedia may be the closest thing to a metropolis yet seen online.”
