Even if the article was entirely positive, I personally wouldn't want anyone to know when and where I was applying. What if I were happily employed elsewhere when that interview occurred? I don't want somebody that didn't hire me to have any sway on my current employment unless it's where I'm working at the time.

In this case, Dan personally reviewed and approved the article, but that wasn't known at the time (nor was it disclosed), so the caution was certainly warranted.
