I have been working in computers and host based systems for the last 12 years. I was running my own Galacticomm BBS out of my parents house when I was 14-15. I had 7 phone lines comming in the house a comm server, I even had a phone number relay on the south side of town to make it local for people who lived south of there.
I am 26 now, and one thing I can tell you the difference in is the "experience" in dealing with customers. I am much more aware of the market and what customers demand and expect from companies such as ours. Especially after had been a consultant for a large Software company, and working in corporate America the last 7 years.
I am not saying a 16 year old is not capable of handling customer issues, however, the "experience and knowledge" is lacking at that age. It's not to say they aren't smart or technical enough, just that the Customer can pick up on it. But lets be honest, at the same time, there are plenty of adults my age and older who don't have the sense of a 10 year old either, so it can go either way
So I think what I am trying to say, is more power to the younger guys ( and gals) trying to pursue a life in business. I commend them. Just don't lose track of your commitments.
