GigaOm head Om Malik and TechCrunch editor Michael Arrington were supposed to lead a talk on the "Cult of Blogging" today at some blog conference in Las Vegas. Neither showed. Om, apparently called in sick, while Arrington, according to Leo Laporte, "forgot" about his commitment. The replacement? A chat with Justine Ezarik, who hosts a lifecasting videoblog under the name iJustine. For attendees who were disappointed by the switch, we offer one consolation: The comely video blogger is far, far easier on the eyes than Arrington or Malik. Hail the new cult leader!
