so you can start a web company,software company where you don't need so much money, rather brain,

I would have thought it would be an advertisers dream to have an audience of serious business minded teenagers. Where else can you get that kind of niche audience. It's easy to advertise to teenagers on fun sites such as cracked, or myspace... but where on the web has the kind of demographic that the above idea is talking about? This kind of highly targeted niche audience is worth huge amounts of money to the right advertisers.
