if you ask me

he showed total command of his stuff, in breadth and in depth on the topic... shot msg yet packed with info and ideas, no non-sense style, probably a MBA with previous engineering background,

(I can bet $1 with you, you won't be able to find a non-MBA who knows both Donnaha and Cargil unless he/she works for that industry, )

he is apparently one person who thinks in English, however his typing fails him more often than he would like, (just as myself)

---------
never question people's credentials based on, "he doesn't sound as holy as I think he should...", because what you think he should do may only be a false impression from someone who is not in that profession,

cheers,
