I learned more about technical writing from
The Elements of Style and a one-semester university course that I ever did from 13 years of public schooling. I learned more about creative writing from being an immortal on a MUD and contributing to the underground newspaper than from anything I ever did in classes.
What I learned from the public school system was that I was not a good writer, and didn't know how to appreciate literature. As it turns out, that was antipodal from the truth. I have since re-synthesized the available data and revised my conclusion: my interests in school simply did not align with the curriculum mandated by school administrators. My grades were a measure of correlation rather than indicative of causation.
For instance, my teachers made me read Dante's Inferno. If Dennis Miller ever dropped the name Vanni Fucci into an obscure joke, I would probably get it, still having vague memories of the Malebolge filled with thieves and bitey reptiles. But I consider Planescape: Torment to be a better work of art. It isn't in a standard poetic form, though. Torment is a bit tougher to read in its entirety, and no one would dare to allude to bronze spheres to make a point without some inkling that the audience has played it. It is one thing to be exposed to art that has been blessed as a canonical masterwork in a controlled, sterile classroom environment: it is another thing entirely to recognize art in the wilds of your own life, and to recognize its worth because you feel emotion in its presence. When the system values the former over the latter, it has failed in its purpose. It failed me.
So I consider myself fortunate that I taught myself to program in BASIC and C many years before my public schooling system decided to offer a programming course in Pascal. Had that been my first exposure to software development, I would certainly not be here, writing this, now.
