INFO SCIENCE: Wikipedia English just hit 500,000 articles:
The Wikimedia Foundation announced today the creation of the 500,000th article in the English-language Wikipedia, its project to create a free, multilingual, online encyclopedia. The article was about "Involuntary settlements in the Soviet Union." The total of 500,000 articles far exceeds any other encyclopedia project. At the average of 2,500 characters per article, this is 1.25 gigabytes of raw text, which if printed double-sided would form a stack about 66 feet or over 6 stories tall. Other recent additions to its English-language edition include hundreds of full-length songs, almost a gigabyte of new images, and subject-specific portals.
My prediction: One million entries in less than three years.
