This is a thoughtful look at the relationship between content and design, and some steps that designers can take to better work with copywriters.
We all know designers and copywriters should not work in silos. We know design and copy should inform each other, rather than one being retrofitted to the other. This is especially true for UX writing, which must work in tandem with design to do its job well. Effective collaboration between design and content, however, is easier said than done.
The author goes on to lay out some ideas to improve collaboration, mostly from the standpoint of the designer, but honestly I think a lot of these same ideas are important for developers. And you can extend it further by saying “don’t use placeholder copy for user generated content”.
