Seems like he's following a ridgid structure in his blog posts (reflection, learning, application). Is this a common framework? I've seen similar things but not this specific one before.

He's not a writer. He may have reasoned that he has lessons to share but lacks writing skills, so he relies on a framework. In art history, some of the greatest painters were people who were witnesses at the right time and place - we love their work today not for their craftsmanship but for their perspective.
