The same law that relates to publishing in the offline world, generally speaking, applies to material posted publicly on a Web log, ... Authors generally are obligated to publish as facts only what they believe to be true.
Huhh? What law says authors have to tell the truth? Many bloggers publish rumors, speculation, parody, fiction, hypotheticals, trial balloons, devil's arguments, and various other deviations from the honest media. The print media have been doing it for centuries. There is no legal obligation to tell the truth in a blog.
