Since 2016 I publish a new blog post once a month. A long lost friend (20 years no contact) found it, read a handful of my deep dives and then offered me what I consider a dream job based on my content and perceived writing ability. I got to jump from an IC track to an executive role. My then company of 15 years did not offer that opportunity. I recommend a blog just to show the world your chops. You don't know who might read it.
