The Oxford guide to concise english says: "expert.
n. A person who is very knowledgeabout or skillful in a particular area.
adj. having or involving in specialized knowledge or skill."

So am I arrogant in assuming that members here are experts? Are you saying that AO has some non-experts too? In my opinion, operating a modern computer is a special skill which many people in this world still can't understand. And I'm not talking about illiterate bushmen from Africa or whatever. I'm thinking about the elderly and those people who never have been interested in this stuff to begin with. I know several people who are amazed about my computer skills. They're not that special compared to anyone else in the same branch but for those who are unfamiliar with computers, it's really amazing.

If computers were magic then I'd just be an amateur magician. But many people will still be amazed by the smallest tricks that I can perform.
So stop thinking that way, ego. Being an expert just means you know more about a certain topic. It doesn't mean you're better than someone else in general.
Aside the poo slinging I consider myself an average person. Im not impressed at all but I too find it amazing that someone would let you operate any sort of machinery yet alone drive. You telling others how they should think... now thats just out of line and down-right insulting.
