Thanks for sharing related articles! I unfortunately don’t know if this is truly a relatively new field – content strategy has been a part of information architecture and this is something that we think about all the time already, namely, thinking about language we use and how we tell a story through taxonomy and structure. Do you mean to say that this is a new stream within that? It also seems like you’re hinting towards technical copywriting in a higher level. I only make this comment because this is extremely crucial part of a product designer’s process. It involves a lot of massaging in the story that we tell.
