As announced last night by Jimmy Wales (video), the Wikimedia Foundation board has passed a resolution on licensing:

• The Foundation requests that the GNU Free Documentation License be modified in the fashion proposed by the FSF to allow migration by mass collaborative projects to the Creative Commons CC-BY-SA license;
• Upon the announcement of that relicensing, the Foundation will initiate a process of community discussion and voting before making a final decision on relicensing.

Read the whole resolution and CC CEO Lawrence Lessig’s explanation.

This is an extremely important step toward a world in which the free content world is not fractured by license incompatibility and thus is stronger.
