I am often mistaken for an “expert,” but no, not in my subject matter: I am merely well-acquainted with the work of many actual experts. I’m a liaison, translator, and popularizer. I’m good at that, and it’s good work if you can get it. Many of the actual experts are also acquainted with me, and they follow and check my work. These days, I can be confident that if I get anything too far wrong, I’ll hear about it from a source I can trust. But the only thing I am truly expert at is the craft of writing and web publishing … and even in that I am humbled by the achievements of others, of course.
