"But the most impotant reason for taking classes in writing is what it teaches you not to do."
impotant -> important
great post, just wanted to point out a typo here: "I cant quote the equations of General Relativity from memory, but nonetheless if I walk off a cliff, Ill fall. "
it should be "I'll fall". good work otherwise.
"I support policy X because it enables economies of scale and I am against polcy Y because it introduces a single point of failure."
polcy -> policy
