I'm not sure what's been the best part of my eight hours in Las Vegas: learning what "fair use" means for bloggers, understanding the true prowess of Technorati or seeing the Bellagio fountains dance to Catherine Zeta Jones singing "All That Jazz."

Thanks to Alissa Krinsky for keeping things going while I'm at Blog World Expo, where tomorrow HDNet's Mark Cuban will be a keynote speaker. Also, tomorrow Alissa will be interviewing Dan Rather as his HDNet show comes up on its one-year mark.
