Breaking news: Wikipedia announces Creative Commons compatibility!

Sylvain (Jamendo’s CTO) just got back from a Wikipedia/iCommons party in San Francisco where he taped a very exciting announcement from Jimmy Wales : Creative Commons, Wikimedia and the Free Software Foundation just agreed to make the current Wikipedia license (the GFDL) compatible with Creative Commons (CC BY-SA). As Jimbo puts it, “This is the party to celebrate the liberation of Wikipedia”.

There is some info from the Online Information conference keynote in the IWR blog.

The InfoToday blog will have more on this later.
