Blogging Legislative Intent

When is a blog legislative history? See Robert Ambrogi:

With the launch of this "semi-official" blog, The Senate Site, Utah's state Senate became the first legislative body to make blogging a tool for lawmaking, Stateline.org reports

"Joining the nation's growing proliferation of political Web logs, or blogs, the Utah site was the first of its kind to strike up a digital dialogue that included entries not just from state Senate Republicans but also from minority Democrats and lawmakers in the opposite chamber. Unfolding comment by comment, the unofficial daily log often paralleled official debate taking place under the dome -- with the added bonus of anonymity."
