Wikipedia Commons reached five million files on 2 September with the upload of File:Kjøbenhavnsposten 28 nov 1838 side 1.jpg. The file, uploaded by Danish Wikipedian Saddhiyama, is a scan of the front page of the first issue of the newspaper Kjøbenhavnsposten, from 28 November 1838. In response to the milestone, articles on the newspaper were created in the English and French Wikipedias; Saddhiyama had created an article in Danish the day before. The new image annotation function has also been used extensively on the image to provide translations of much of the Danish text in the image, which features an article about democracy.
Study estimates 0.4% of articles, 1.3% of views have vandalism
Robert Rohde (User:Dragons flight) has created a new analysis of vandalism on English Wikipedia by analyzing reversions in article histories from a mid-June database dump. Rohde's initial results, tabulated at Wikipedia:Vandalism statistics and described in more detail in a mailing list post, indicate that over the first half of 2009 about 0.2% of all mainspace page (including redirects) were in a vandalized state at any given time, or about 0.4% of all articles (assuming that redirects are rarely vandalized).
