<ironic mode on> Steffen has a blog in German on TechNet. I don't speak German, and online translators I have found are woefully inadequate for technical writing. Interesting tho that his title is "Technologieberater".
Online dictionary defs for "Berate" include "to scold; rebuke; censure severely or angrily". Contrast with the oft-found title FOOtechnology "Evangelist", which online sources define as "writer of Christian Gospel; Christian who converts others; and A person doing religious or charitable work in a foreign country."<ironic mode off>
