By Edwin Black Jay Leno probably said it best a few weeks ago when he joked that when Wikipedia's servers briefly went down for some three hours, it left the world without a source for false and erroneous information. But many in our information-driven society believe it is no joke. A growing community of the informed believes that Wikipedia, the constantly-changing knowledge base created by a global free-for-all of anonymous users, now stands as the leading force for the dumbing down of world knowledge. If Wikipedia's almost unstoppable momentum continues, critics say, it threatens to quickly reverse centuries of progress in the sharing of verifiable knowledge with its highest aspiration being genuine fact. In its place would be a constant cacophony of fact and falsity that Wikipedia's critics call a “law of the jungle.†By way of background, Wikipedia's 2.3 million-plus unvetted entries are contributed by anonymous users known only by colorful and sometimes bizarre and shadowy pseudonyms, often in a sort of “anything goes†perpetual intellectual wrestling match.
