Wikipedia rules the world...

everything i learned in college is of no use now

Or on SO

yeah, pretty sure it can't, unless you did a degree in general knowledge.
even if all the parts are there, the way it's bought together is what makes a course.

knowledge should be free, what differentiate ppl is the skill to locate the needed knowledge and apply it asap to solve problems at hand.

what I mean for engineers are the speed of following process :
Google → SO → Ctrl C → Ctrl V → git commit
