Wikipedia Hits Million-Entry Mark

What started off as an ambitious experiment (at least in my mind, that's what it was) has become one of the most accessed reference sites on the Internet. As librarian, I have to ask if that is a good thing? Still, I find Wikipedia to be an extremely valuable resource as long as I remember that it has a different definition of authority than other traditional reference works. For example, you trust the information in the Encyclopedia of Religion because it is edited by Mircea Eliade of University of Chicago fame. In contrast, you trust the information in Wikipedia because of community consensus.
