Don't worry. I chose the term "educator" over "teacher" or "expert" for that very reason: namely that neither having a degree in Education nor a PhD in physics makes you a particularly suitable physics educator. KA needs people who can do for biology, neuroscience, history, and so on what Khan can do for college physics and maths.
I suspect that they're going to be PhDs and practitioners as opposed to K-12 schoolteachers -- but I really don't give a damn about credentials. There are fantastic high school teachers out there. There are PhDs and masters in their respective fields who are ridiculously bad educators, especially at the level of teaching that KA provides.
