College or University education is more than the "education". It's a way of life that people go through to gain some incredible social experiences that you can't get elsewhere. Now I agree that we always need to improve our education, but for the "college is worthless" because it doesn't help your career type, a great college(not a vocational school) is never for your career, it's for personal growth.
On a different note, do people notice that there are more and more teenagers using HN? I feel like HN is the new Myspace again.
