Sorry! HP:MoR = Harry Potter and the Methods of Rationality, a fanfic by Eliezer Yudkowsky.

This inspired me to start brainstorming a book designed for more logically-minded and less emotionally-conscious people on how to communicate with those who are the other way around. I may at some point try to pick the brains of folks here about that.

I look forward to that! You may want to know that a lot of those communication methodology issues have been talked about (though certainly not exhaustively) in the "Craft and Community" sequence.

It went a long way towards getting me out of a frustrated "oh-god-this-is-hard-and-there-is-so-much-more-to-learn" funk.

Well done! I'm still in that funk with my mando, alas.
