Confused laughter

My old friend Erik sent me this link and I had to read it several times.

Yes, it is a real Microsoft page. Yes, they carefully explain how to become competent in using humour. With a development plan. And testable proficiency levels from “Basic” to “Expert”. With a reading list. And without the slightest attempt at levity.

So do the authors lack humour from the outset, or did a committee carefully go through the text, removing any “untimely or inappropriate humor”? Or is this an elaborately set-up meta-joke, poking extremely satirical fun at the perceived lack of humour of Microsoft? My head spins, I feel like laughing, but don’t know if I dare to.
