This is more of a startup response than web design specifically. I'm 17, been working on projects for a few years now. The barrier to entry on the internet is low these days, which is great as it means anyone. Not just teens but maybe someone who wouldn't usually be able to start this kind of thing is able to do so.<p>Sites like Forrst, Dribble and TinyProj (newcomer) are pushing this growth and building a portfolio/experience based credibility system whereas designers are evaluated by their design work, not their degree.
