GFDL and Wikipedia Relicensing

Version 1.3 of the GFDL was released today. Section 11 contains directions for Relicensing, giving “Massive Multiauthor Collaboration Sites” (why can’t Richard just call them wikis like everyone else?) like Wikipedia the option to change away from the GFDL and adopt CC-By-SA as their license. This is a glorious day for license incompatibility in the open content world, and one I had thought we might never see. Creative Commons also has coverage. Now the Wikipedia community just needs to choose/decide to relicense its work CC-By-SA.

What does it say about a license when it’s most anticipated new feature is a way to migrate away from it?
