Netflix has finally launched an official blog, but with a unique focus. Instead of being about the company, or the rental experience, or about movies, The Netflix Community blog is devoted only to the Community features of Netflix (Friends, Profiles, custom lists, etc) and we who use them. It's where you can go to discover new features or changes to existing ones, and give feedback.
Unlike Hacking Netflix, or this blog, the Netflix Community blog is written by folks who work for Netflix, "by the team that is building the social elements of the Netflix site," so it's the horse's mouth.
