Our largest project by far is [http://www.wikipedia.org Wikipedia], the free encyclopedia. Started in January 2001, it celebrated one million articles in over 100 languages in September 2004. In this time, Wikipedia has also become one of the 500 most popular websites in the world (source: [http://www.alexa.com/data/details/traffic_details?&range=2y&size=large&compare_sites=&url=http%3A%2F%2Fwww.wikipedia.org%2F#graph Alexa Internet analysis of Wikipedia traffic]).
