This is a humor piece, not a guide (for HN readers who click on comments first).
My favorite? Rule No. 10: Revise, revise, revise.
I can't tell you how many times I've written something, had it published (through the newspaper I work at), then read it 2 weeks later and thought "DAMN! I should have changed that!!"
I do have a habit of reading partially through an article and then commenting ...
For example, "Rule 8. Is Secret" is (possibly) illustrating #6, #4, and the humor of it #3.
It's making points, meta-points, and doing it with a sense of humor. There are good lessons at each of those levels, and it makes you think "Wait, really? Did he really mean that?"
