Achieving and maintaining any level of expertise requires ongoing awareness of what you don't already know, as you wisely point out. I reckon that's as true for experts as it is for aspiring experts and big daddy.

I personally think that understanding how the many individual elements of a technlogical system work, and then understanding how they fit together, is impossible to achieve using any single and convenient source. Formal edumacation, experience, practice, spending days wrestling with systems that refuse to work, reading manuals, re-explaining things to others, reading magazines like MM, internet research are all parts of the learning process.

If you have any suggestions as to which particular bits of Klingon are currently standing in the way of your personal progress, this is certainly a good place to discuss them in more detail. Essentially, MM can't be expected to know which subjects you don't know enough about, unless you're prepared to list them.
