It is somewhat puzzling to me that my PredictionBook evangelizing is well received here

This particular shame based instance of evangelism isn't well received.

Frankly, it is a scandal to Less Wrong that its high-karma members don't bother to publicly record their own predictions and yet continue to expect others to believe in the efficacy of the techniques taught in its core texts like The Sequences.

Eliezer frequently makes predictions and even bets. Luke makes predictions from time to time as well. Not sure about Yvain. Your complaint seems to be that they don't happen to personally use your preferred website.

As far as I'm concerned you would have struggled to have come up with a more powerful way to persuade us to not use prediction book.
