I'd just as well the Star Trek ranks from the first of April were still in place. Our forum ranks may signal levels of expertise, but most of us are known by the advice we give: Patio and Broni for all 'round expertise, evilfantasy for malware expertise, kpac for web page knowledge, and several for batch file expertise. (I leave out many names, and I apologize.)
Me? Well, I try to throw out some pertinent questions every now and then, and I'm really good at recommending you not flash the BIOS of your computer -- unless it's absolutely a last resort -- and I'm not sure I like it, even then!
Sure, I like that I rank "Specialist," and that i'll have another in less than one hundred posts, but if someone were to ask if I consider myself a computer specialist, I'd emphatically say, "No."
The long and short of it, is that most of us do not act, or portray ourselves, outside our areas, or above our levels, of expertise.
