The document discusses the need for content management systems to embrace flexibility and adaptability to allow content to be published across different interfaces. It introduces Novius OS as a content management system built with this principle in mind, allowing content created once to be published everywhere through its use of "content nuggets" that are separated from presentation and can be reused across different applications and channels like blogs and social media. The system is demonstrated with an example of content flowing from a database to a blog post to Twitter.
