This Fast Company article should have been titled "How to Launch a Career with your Blog if you are a Writer". And also, there really was no "how" in there; just examples of the fact that you could. If you were already a famous blogger.
It would be interesting to see more writing about how to "launch a career", "expand a career", whatever using a blog when the career is actually in industry. So how does a marketing professional use a blog to take a next step in their career? I'm not sure if I am trying to convince myself to write something. I think I did write something in the past with the focus on being "findable" and "credible".
Anyway, this Fast Company article kind of left me feeling "that's great for them but what about me?"
