This. Unfortunately it appears that these days if you want to get ahead in your career is to publish content and develop that "personal brand".
Of course your work can speak for itself, but who can hear it? Advertising through technical writing seems to be a very good thing as long as its valuable and honest. Because if it isn’t we filter it out.
