If you're heading to Vegas to cover BlogWorld & New Media Expo—"the world's first, industry-wide blogging tradeshow"—be sure you're properly credentialed. "Press credentials are open only to accredited members of the professional media and will require submission of articles and verification that you intend to write for a publication on the conference." Good idea! You don't want those untrustworthy, parasitic bloggers covering the event, would you? [Information Week, via]
