The good folks working on HD DVD at Microsoft have started a blog called "The HD DVD Insiders" - it's starting out small, but for the Home Theater geek and industry pro alike, I expect this is going to become a popular site to supplement the AVSForums so many of us enjoy for the inside scoop.  Not much content yet, but Ben and others tell me they have podcasts, interviews, Q&A's and more in store.  Subscribed.
