I work as a UX Strategist and always have a content audit performed before I begin any UX project. I've always referred to the planning, arrangement and writing of the content afterwards as Content Strategy. I've notice on this site that there is no content strategy only Content and Content-Management.
I would consider content management as the working with content once the strategy has been written. There are even more than a few posts here that refer to Content Strategy yet no tag. Is content-management and over-arching term that contains content-strategy or are they synonymous or are these two different fields entirely?
