Creative Commons and Bzzagent broke up.

Lawrence Lessig listened to the comments and roar of outrage that happened when they announced that BzzAgent has partnered with Creative Commons, and have now reconsidered. They decided to not take BzzAgent up on their offer of free WOM for a month. See the Lessig Blog for his "Advice taken" post.
Much chatter on the wires about Creative Commons happened due to all of this though, it's worth popping by just a gwai lo to read An Idea So Good That It’s Worth Spending Time Explaining Without Expecting Something in Return.
