I think a lot of readers are missing that names are changed (as is mentioned at the top of the blog post... you aren't actually named "Jon", right?); this is not a "public shaming" but a peek into this particular and one-time-only motivational strategy.

My personal thought is that with some relatively minor modifications, this could work as a pretty powerful motivator.

The points of "I'm trusting you completely; you don't have to run your decisions by me; I recognize that I do and will owe you enormously if we all manage to pull off what we said we would" is not bad at all, and would motivate me.

It's not the kind of thing you can pull out every two months -- that would be horrible -- but it sounds like he's asking for a complete commitment for a short burst of time, and also recognizing that this is costly in many ways.
