The end of Wikipedia ?

The online encyclopedia is suddenly adding fewer articles and has fewer editors. Has all knowledge been summarized, or does Wiki have a problem ? Up until about two years ago, Wikipedians were adding, on average, some 2,200 new articles to the project every day. The English version hit the 3 million mark in August 2009. But early in 2007, something strange happened : Wikipedia's growth line flattened. It remains a precious resource - a completly free journal available to anyone and the model for a mode of line collaboration one hailed as revelutionary. Still, Wikipedia's troubles suggest the limits of Web 2.0 - that when a idealized community gets too big, it starts becoming dysfunctional, just like every other human organisation.
