Couldn't you broaden the question? There are probably a few people on here who aren't IT professionals but have some other technical qualifications.
I thought I left it wide open.
Essentially, if you are paid to service, support, repair, develop, install etc hardware and or software I would consider you to meet the intent of the question. The purpose of phrasing it the way I did was to put a seperation between those of us who have technical knowledge (but are self certified as knowing something about computers) and those who have an external certification in that some one is willing to pay for their expertise.
Not implying that we don't have some really sharp and knowledgeable people who just happen to earn their living in some other way. Only trying to get a hard number to dispel this notion that Mac users are inherently non-tech.
From my experience, and the early poll results, this is definitely not true.
EDIT: As far as other technical qualifications, I agree we have those in plenty. I'm an engineer and have certifications in Systems Engineering, plus in a previous life (many years ago, but not on a distant planet) I was a Radar Repair Tech in the Air Force. Still, I do not meet my criteria so I am one of the No results in the poll.
