Neither a college education nor continued employment in the field is a requirement to ask a stackoverflow question. In fact, I'd venture to say that a version of stackoverflow where the default answer to everything was "you should have learned this in college" would not be very useful (or used) at all. If you find the discussion beneath you, I suggest that you not participate and find a better use of your time. Others may be getting value from it and I can't for the life of me understand why you think this is a bad thing.
