Presentation matters. Good documentation is evidence of a library that has been carefully thought through. Slop in the readme suggests slop in the code.
Unfortunately college puts up the same barriers. Much of the time I spent in high school learning to code was for nothing, because my university wouldn't let me even attempt to test out of the first- and second-year courses. In another instance they also wouldn't let me count a graduate statistics course for a baby-stats elective requirement. "We WoULdn'T bE an AccREdiTeD iNStiTutION if wE lEt yOU do THat!"
I ended up majoring in math instead of compsci as a result. It ended up being a good choice, because now I have skills in both areas. But I was pretty disappointed as an incoming freshman, enthusiastic about computer science, that college was nothing like what my parents and teachers made it out to be.
