Even college grads can follow some of this advice. Come out of school ladened with debt is no picnic and sure going straight to a startup sure seems like a sexy idea but even Paul Graham admits most startups fail. Sure valuable experience, and new contacts help ease that but there are alternatives. I would prefer to go into business for myself once I am debt free and on solid footing (not waiting because I am scared....well I am a little)
Not to mention that above average coders can make some good salaries.
