We need to embrace the idea that UX is necessarily multi-disciplinary—not just within different communities of practice, but within individual skill sets. People are surprised to hear that I speak at conferences about content strategy and yet still do interaction design work for clients. Why can’t I love them both? I loved them both when I called them information architecture.
So that’s why I hope that everyone working in this space feels like they have the potential to develop skills in multiple areas. You can be an interaction designer and a content strategist. You can be a user researcher and a visual designer too! You can even still be an information architect.
Though I agree with this article, I still think that there are people who are more comfortable and who possibly do better work in certain parts of the discipline. People who are great at user research/testing, people who like to deal in content, people who like to deal in function, etc. In general, I think you excel more at what you like, and what you are more naturally inclined to do. But, someone who focuses on content is no less valuable than the person who does application design.
