According to the site:
The English Wikipedia alone now has more than 920,000 articles, with over 340,000,000 words. The millionth article is expected to appear in late February or early March. The combined Wikipedias for all languages have an estimated total of over 3,100,000 articles in some two hundred languages. Eighty-four of the non-English Wikipedias have over 1,000 articles, thirty-six have over 10,000 and seven have over 100,000.
I take this opportunity to thank everyone who has behind this wonder-of-the-internet (IMHO) for their incredible work.
