A post at Dirson kicked off a Slashdot discussion about Google offering to host "some" Wikimedia content. What this precisely means is not spelled out. A post on the Wikimedia wiki says that "terms" of the offer are being discussed and that a private IRC meeting is scheduled for March. It also mentions that Google's offer "does not mean" there will be a requirement to include advertising on Wikimedia sites. Stay tuned.
Wikipedia and other Wikimedia content is currently accessible via Google from one of the many services that host the content. Wikipedia material is also included with many of the dictionary definitions linked to each search term via Google's new relationship with Answers.com. The new MSN engine offers "direct answers" powered with material from Microsoft's Encarta encyclopedia. Yahoo! provides material from the Columbia Encyclopedia on a serp when a shortcut (the word "facts") begins the query string. The encyclopedia can also be searched on the Yahoo Reference site.
