I appreciated the snarky language, but a few things made me wish I hadn't read this. Leaving aside the humble brag about their engagement on LinkedIn, I am not a fan of marketing in general, product or otherwise. Furthermore the use of images in this article I found cringeworthy, and I did not need to see a cute picture of the author's children, which seemed ... gratuitous and manipulative?
The title is clickbait, and I feel bad for being duped into reading something I had zero interest in. "Why I'm Starting a Blog about Product Marketing" would not have been a link that I would have clicked on.
