Insider trading is trading with what is termed "inside information". I was a naïve college student when I first heard this cute expression. At that time, I was shocked to learn of the illegality of the practice. The "placement" office at school was (and still is) in fact an "advice office". Like any entity dispensing career advice, it stressed the paramount importance to the career seeker of what is called "networking", which is to say getting in with one or more cliques. The motivation for all this networking is the fact that a sizeable number of employment opportunities go unannounced in advertising or other published form...information about their existence is "inside information". Possession of inside information is forbidden when seeking income through investment and required when seeking it through work. How interesting.
There's more to commerce than investment. To OpenCommerce to outsiders is to expand the frontier of OutsiderTrading beyond trade in financial paper. Hopefully someday OutsiderTrading will be the accepted standard in everything from soup to nuts.
